Ibm Advancing On Its Search Engine Project

IBM would like to see its WebFountain supercomputing project become the next big thing in Web search.

The Internet can be a treasure trove of business intelligence–but only if you can make sense of the data.

Along with competitors such as ClearForest, Fast Search and Transfer, and Mindfabric, Big Blue hopes to foster demand for new data-mining services that ferret out meaning and context, not just lists of more-or-less relevant links.

It’s a tall order, one that’s pushing the limits of supercomputing design and stretching expectations as to what raw processing power can accomplish when set to work on the world’s largest document library. Traditional search engines such as Google are already hard-pressed to match search terms to specific Web pages. Now WebFountain and other projects will take on a task that’s exponentially more complex.

“Search is trying to find the best page on a topic. WebFountain wants to find the trend,” said Dan Gruhl, chief architect of the project at IBM’s Almaden Research Center in South San Jose, Calif. Harnessing the Internet’s data to find meaning is a visionary ideal of Web search that has yet to be attained. As more companies manage their businesses on the Web, however, analysts predict they will be looking to extract value from its bits and bytes, and many software companies are now examining ways to bring that value to them.

IBM is hoping to cash in on the trend with the four-year-old WebFountain project, which is just now coming of age. It’s an ambitious research platform that relies on the Web’s structured and unstructured data, as well as on storage and computational capacity, and IBM’s computing expertise.

Whether WebFountain can deliver today, the problem it hopes to crack holds particular attractions for IBM. Big Blue has been pushing a new computing business model in which customers would rent processing power from a central provider rather than purchase their own hardware and software. WebFountain dovetails nicely with this utility computing model. IBM hopes to use the project to create a platform that would be used as a back end by other software developers interested in tapping data-mining capabilities.

In one of the first public applications of the technology, IBM on Tuesday teamed with software provider Semagix to offer an anti-money-laundering system for financial institutions, with Citibank as its first customer.

The two companies have quietly been working together for months to develop an application that helps banks flag suspects attempting to legitimize stolen funds. Those efforts are in accordance with the USA Patriot Act, signed into law two years ago to fight terrorism.

The WebFountain-Semagix system automates a process that has previously fallen onto the shoulders of compliance officers, who manually compare a person’s name against lists of known suspects.

“This is a classic IT solution,” WebFountain President Rob Carlson said. “It’s not replacing people, rather it organizes unstructured information from the Web to the point they can look at what’s important rather than sifting through a lot of data and manually trying to figure out who’s related to whom.”

In a sign of growing demand for money-laundering filters among banks, Fast Search and Transfer recently announced that financial institutions could build a similar application, and Cap Gemini is said to be a first customer, according to analysts.

WebFountain traces its roots back to Stanford University and another groundbreaking research tool, Google. Its origins lie in a scholarly paper about text mining–authored jointly by researchers at IBM’s Almaden site and at Stanford–that discusses an idea known as hubs and authorities.

That theory suggests that the best way to find information on the Web is to look at the biggest and most popular sites and Web pages. Hubs, for example, are usually defined as Web portals and expert communities. Similarly, the concept of authorities rests on identifying the most important Web pages, including looking at the number and influence of other pages that link to them. The latter concept is mirrored in Google’s main algorithm, called PageRank.

IBM applied the same concepts in an early Web data-mining project called Clever, but shortcomings eventually led researchers to turn the theory of hubs and authorities on its head. In short, IBM found that it could excavate more interesting data from pages that the theory of hubs and authorities normally pushed to the bottom of the heap–unstructured pages like discussion boards, Web logs, newsgroups and other pages. With that insight, WebFountain was born.

“We’re looking at…the low-level grungy pages,” said Gruhl. Analysts said they expect to see increasing demand from corporations for services that mine so-called unstructured data on the Web. According to a study from researchers at the University of California at Berkeley, the static Web is an estimated 167 terabytes of data. In contrast, the deep Web is between 66,800 and 91,850 terabytes of data.

Providing services for unstructured-information management is an estimated $6.46 billion market this year and a $9.72 billion industry by 2006, according to research from IDC.

Any doubts about the scale of processing power required to tackle this task are quickly dispelled with a visit to WebFountain’s server farm, housed at IBM’s Almaden Research Center.

The company employs about 200 researchers in eight research labs around the world, including in India, New York and Beijing. But the heartbeat of the operation is here.

After clearing a gated security checkpoint, guests follow a long driveway to a low-slung, 1960s-era office building tucked away behind rolling foothills and parklands above Silicon Valley.

The steady whirr of fans signals the presence of something big down the hall.

A main cluster consists of 32 eight-server racks running dual 2.4GHz Intel Xeon processors, capable of writing 10GB of data per second to disk. Each rack has 5 terabytes of storage, for a total of 40 terabytes for the system.

The central cluster is supported by two adjacent 64 dual-processor clusters that handle auxiliary tasks. One bank crawls the Web–indexing about 250 million pages weekly–while the other handles queries.

The three clusters together currently run a total of 768 processors, and that number is growing fast.

The cluster and storage is migrating to blade servers this year, which will save space and provide a total of 896 processors for data mining and 256 for storage. In total, the system will add 1,152 processors, allowing it to collect and store as many as 8 billion Web pages within 24 hours.

Like Web search engines, WebFountain can be used to try to find a needle in a haystack, but unlike Web search, it’s designed to scope back and identify trends or answer unknowns like, “What is my corporate reputation?”

That goes well beyond the capabilities of Web search engines developed by companies such as Google, Inktomi and Fast Search and Transfer. These products typically scour the Web to find the documents that best match a given query, typically analyzing links to important Web pages or matching similar chunks of text. With these and other methods, search lets people browse, locate or relocate information, and get background information on a topic.

By contrast, IBM’s WebFountain wants to help find meaning in the glut of online data. It’s based on text mining, or what’s called natural language processing (NLP). While it indexes Web pages, it tags all the words on a page, examines their inherent structure, and analyzes their relationship to one another. The process is much like diagramming a sentence in fifth grade, but on a massive scale. Text mining extracts blocks of data, nouns-verb-nouns, and analyzes them to show causal relationships.

WebFountain promises to combine its intelligence with visualization tools to chart industry trends or identify a set of emerging rivals to a particular company. The platform could be used to analyze financial information over a five-year span to see if the economy is growing, for example. Or it could be used to look at job listings to pinpoint emerging trends in employment.

“The Web has become just a huge bulletin board, and if you can look at that over time and see how things have changed, it answers the question, ‘Tell me what’s going on?’” said Sue Feldman, analyst at market research firm IDC. “This looks for the predicable structure in text, and uses that just the way people do, to do some analysis, categorize information and to understand it.”

To be sure, some critics say WebFountain and other projects still have a long way to go in proving they can deliver on their ambitious promises.

“IBM is trying to unleash this cannon of 20 years of research–it’s a nice big gun, but it may be ill-suited to the task in some cases,” said Jim Pitkow, president of search company Moreover, which has a deal with IBM rival Microsoft. He argued that companies may not need to have 3 billion pages crawled in order to do an analysis of their corporate reputation or marketing effectiveness online, because many pages don’t address the topic.

“Automatically detecting sentiment is a tricky thing,” Pitkow said. IBM says the WebFountain service has already yielded some promising results in early test runs, pointing to 2002 market research done on behalf of oil conglomerate British Petroleum as one telling example.

BP already knew that gas prices and car washes are customers’ chief concerns while at the pump. But by unearthing news of a tiny Chicago-area gas station that created “cop-landing” areas for police officers, WebFountain called attention to another consumer worry: crime. Now BP is exploring plans to improve safety at its stations, giving away coffee, doughnuts and Internet connections to attract police officers.

Other WebFountain developments include an application expected to make its debut this summer from Factiva, an information retrieval company owned by Dow Jones and Reuters. Factiva licensed WebFountain in September and has been building software to sit on top of the platform and gauge corporate reputation.

In an era of corporate scandals and fierce competition, measuring public perception could become a key focus of many companies. Already, at least one company that has tested WebFountain has named a corporate reputation officer, according to Gruhl.

“The problem has always been the difficulty of doing systematic mining of such a large amount of data, and distinguishing the important from the trivial,” said Charles Frombrun, executive director of the Reputation Institute.

“If the venture works out,” Frombrun said, “there should be a great deal to learn from combining retrospective data from print sources with emerging data from Web analyses.”

6 Considerations When Evaluating An Intent Data Source

6 Considerations When Evaluating an Intent Data Source John Steinert


Share This Post

Whether you’re new to intent or have been experimenting with different sources for a while, our clients have found it helpful to evaluate potential additions to their stacks in terms of six considerations.

The first 3 intent data considerations here speak directly to the overall importance of intent data and the last three focus more on its specific value to sales teams.

How intent data can drive real change and better outcomes for your organization #1 – Actionability

One huge difference between behavioral data and many of the feeds you might pump into your stack is that it changes so rapidly. Given this rate of change, to maximize value, the data has to both inspire you and enable you to act with confidence.  When adding a data source, make sure it provides everything you need to react quickly to new insights.

#2 – Substance

There’s plenty of data available around that might increase what you know about a particular account. The question you need to be asking about any data source is whether or not the addition will truly help to either reinforce your current decisions, or conversely, provide a good rationale for near-term changes. If a new source lacks the precision necessary to change your own behavior in some substantive way, it may just be another “nice to have” that you can do fine without.

#3 – Revenue

When your marketing team becomes better aligned with sales, its inspirations and instincts undergo real change. Instead of being obsessed only with outputs, marketing too becomes focused on business outcomes. This starts delivering more real opportunities into the pipeline. Even more, it means delivering more revenue out the end. Purchase intent data’s primary purpose is to deliver more revenue to your company. Before adding it to your stack, make sure you understand clearly how directly and quickly that added data can make that a reality for you.

Real intent accelerates sales success by exposing the buying behaviors and sentiments of a buying team

Great salespeople are super-adept at turning opportunities into closed/won deals. They’re better than most at assessing need and they’re experts at engaging very specific people with highly relevant outreach. They’re able to adjust and refine their interactions quickly. They create far more win-win conversations across buying teams.

Real intent data accelerates sales success precisely because it supplies the right intelligence a seller needs to make them better at doing their job. So to deliver on this promise, real intent data must obviously be:

#4 – Relevant and accurate

While it can be argued that any information about an account could be useful to a seller, in practice, more information isn’t necessarily better. It takes time to process. It can lead to missteps caused by a perception that a topic matters to the prospect when it really doesn’t. It can waste time.

If the data source is not exceptionally relevant to the types of conversations that sellers use to gain meetings and create opportunities, chances are it’s not as useful as the supplier suggests.

#5 – Precise and prescriptive

Once you’ve made sure that a data source can be vetted appropriately for GDPR, CCPA and other evolving privacy concerns, you can begin evaluating it in terms that matter to your user constituencies.

In jobs where time is especially costly – like many sales functions — the more specific your inputs can be, the better. Behavioral signal sources that come packaged with words like “may” or “seem” or “usually” and the like can easily confuse your colleagues. Instead of immediately taking action, they need to evaluate the material and think through how to incorporate it. This costs precious time.

When evaluating a source of data, look closely at how precise it is. Determine exactly what it can tell you that will be immediately useful to a salesperson. Look for information that they can use that will change what they otherwise would do or say. If the data is not precise enough, it won’t drive change. The right data is like a prescription – it should be obvious that if you use it, you will have a better chance at success.

#6 – Information rich

We strongly recommend that all clients have good data hygiene processes in place because that will raise the overall average usability of each prospect or contact record available to your marketers and sellers. But for most companies, given resource pressures, data hygiene alone is not enough to raise productivity to where it needs to be.

Out of the gate, a good intent data source clearly separates your prospecting names into two very distinct groups – 1) those not currently showing purchase intent who demand less of your immediate attention and 2) those that are showing purchase intent who you need to focus on if you want to grow more revenue and share.

Simply pointing your users towards the right accounts is only one small step better than a broad TAM (total addressable market), a well-defined ICP (ideal customer profile) or even within your named- or target-accounts ( that you’re using for account-based marketing (ABM) or very specific sales programs). The right data source can take you beyond a directional ranking of accounts all the way down to what your prospects actually care about from a variety of angles.

That’s how your teams can best discover more opportunities far more efficiently. Each account might have hundreds of possible contacts within it showing light search behaviors. You need to know which ones actually matter.

With technology changing and converging faster and faster, broad search terms aren’t enough because each account may show interest in any number of generally related interests. You need to know exactly what the real researchers are actually reading.

And if your chances change given who else is under consideration, the more you can know about your competition in the context of a developing deal, the better prepared you will be. These 6 intent data considerations will hopefully equip you to make the right decisions when it comes to adding a new intent data source into your stack.

Priority Encoder In Digital Electronics

In digital electronics, an encoder is a combinational logic circuit which accepts inputs as decimal digits and alphabetic characters, and produces the outputs as the coded representation of the inputs. In other words, an electronic combinational circuit that converts numbers and symbols into their corresponding coded format is called an encoder. The operation performed by the encoder is called encoding which is a process of converting familiar numbers and characters into their equivalent codes.

An encoder has 2n input lines and n-output lines. At a time, only one of the 2n input lines is activated. The coded output of the encoder depends upon the activated input line. There are several types of encoders available such as “octal to binary encoder”, “decimal to BCD encoder”, “keyboard encoders”, etc.

What is a Priority Encoder?

In case of an ordinary encoder, one and only one decimal input can be activated at any given time. But in the case of some practical digital systems, two or more decimal inputs can unintentionally become active at the same time that might cause a confusion. For example, on a keyboard, a user presses key 4 before releasing another key 2. In such a situation, the output will be corresponding to (6)10, instead of being (4)10 or (2)10. This kind of problems can be solved with the help of priority encoder.

In digital electronics, a combinational logic circuit which produces outputs in response to only one input among all those that may be activated at the same time is called a priority encoder. For this, it uses a priority system, and hence it is named so.

One most popular priority system used is based on the relative magnitudes of the inputs. According to the priority system, the decimal input having largest magnitude among all the simultaneous inputs is encoded. Hence, as per this priority encoding system, the priority encoder would encode 4 if both 4 and 2 are active at the same time.

In some practical systems, priority encoders have several inputs which are routinely active at the same time. In such cases, the primary function of the encoder is to select the input with the highest priority. This function of the priority encoder is known as arbitration. For example, in a computer system, multiple input devices are connected, and several of them may try to supply data to the system at the same time. In this case, the priority encoder is responsible for enabling that input device which has the highest priority among all the input devices.

Types of Priority Encoders

Several types of priority encoders are there. Some most important types of priority encoders are listed and explained below.

4 Input Priority Encoder

Decimal to BCD Priority Encoder

Octal to Binary Priority Encoder

Let us discuss each type of priority encoder in detail.

4-Input Priority Encoder

The logic circuit of the 4-input priority encoder is shown in Figure-1.

It has three outputs designated by A, B, and V. Where, A and B are the ordinary outputs and V is the output that acts as a valid bit indicator. This third output V is set to 1 when one or more inputs are equal to 1. In the case, when all the inputs to the encoder are equal to 0, there is no any valid input, and thus the output V is set to 0. The other two outputs, i.e. A and B of the encoder are not determined when V is equal to 0. Therefore, when, V is equal to 0, the outputs A and B are specified as “don’t care conditions”.

The truth table of the 4-input priority encoder is shown below.

Inputs (× = Don’t care) Outputs

I0 I1 I2 I3ABV






From this truth table, it can be observed that the higher the subscript number of the input, the higher the priority of the input. Thus, the input I3 has the highest priority. Therefore, regardless of the values of other inputs, when the input I3 is equal to 1, the output for AB is 11, i.e. 3. The input I2 has the next lower priority, and then I1, and finally I0 has the lowest priority.

We can write the Boolean expression for outputs A, B, and V from the above table as follows,





Hence, the condition for the output V is an OR operation of all the input variables.

Decimal to BCD Priority Encoder

This type of priority encoder performs the function of encoding the decimal digits into 4-bit BCD (Binary Coded Decimal) outputs. As it is a decimal to BCD priority encoder, therefore, it produces a BCD corresponding to the decimal digit of highest priority among all the inputs and ignores all others.

The truth table of the decimal to BCD priority encoder is given below.

Decimal Inputs (× = Don’t care) BCD Outputs

I1 I2 I3 I4 I5 I6 I7 I8 I9 A3 A2 A1 A0











The truth table of the decimal to BCD priority encoder clearly shows that the magnitudes of the decimal inputs determine their priorities. If any decimal input is HIGH, it will be encoded if all other higher value inputs are LOW regardless of the state of all lower value inputs.

Octal to Binary Priority Encoder

This type of priority encoder is used to perform encoding of octal code into binary code. Hence, this type priority encoder has eight inputs and three outputs that produce corresponding binary code as given in the truth table below.

Inputs Outputs

I0 I1 I2 I3 I4 I5 I6 I7 A2 A1 A0 V










This is all about the priority encoder and its major types in digital electronics.

Understanding The Basics Of Data Warehouse And Its Structure


Nowadays, the corporate environment changes according to technology. Organizations are converting them to cloud-based technologies for the convenience of data collecting, reporting, and analysis. This is where data warehousing is a critical component of any business, allowing companies to store and manage vast amounts of data. It provides the necessary foundation for businesses to make informed decisions and gain insights from their data. Data warehousing has become even more important with the increasing demand for more comprehensive data analysis.

Learning Objectives

Understanding the Basics

What are the various types of data warehouses and their characteristics?

Understanding the three-tier architecture of data warehouse.

What is the need for a data warehouse?

This article was published as a part of the Data Science Blogathon.

Table of Contents What is a Data Warehouse?

A data warehouse is a database used for reporting and data analysis. It is a centralized repository for storing, integrating, and analyzing large amounts of data from various sources.  A data warehouse typically stores data from multiple sources in a format that can be easily analyzed. Subjects, such as customers, products, or sales, typically organize the data in a data warehouse.

A data warehouse can be used to support a variety of reporting and analysis needs, such as financial reporting, sales analysis, and marketing analysis. It can also support operational decision-making, such as inventory management and capacity planning. This is a valuable asset for any organization that needs to make data-driven decisions. It can help an organization make better decisions by providing a centralized data repository that can be easily accessed and analyzed.

Various Types of Data Warehouses

There are several types of data warehouses, each with its own unique characteristics and use cases:

Enterprise Data Warehouse (EDW):A centralized repository that collects data from various sources within an organization to support decision-making across the enterprise. EDWs are typically large and complex and are used by multiple departments and business units.

Operational Data Store (ODS):An intermediate store for real-time data that provides a consolidated view of data from various operational systems for reporting and analysis. Unlike EDWs, ODSs are optimized for real-time performance and are typically used for near-real-time reporting.

Data Mart:A subset of an EDW optimized for a specific department, business unit, or line of business. Data marts are smaller in size and less complex than EDWs and are used to meet individual business units’ specific reporting and analysis needs.

Real-time Data Warehouse: A data warehouse optimized for real-time data processing and analysis. Real-time data warehouses are typically used in time-sensitive industries such as financial services and telecommunications.

Cloud Data Warehouse: A data warehouse hosted on a cloud-based infrastructure, such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud. Cloud data warehouses provide scalability, flexibility, and cost-effectiveness compared to traditional on-premises data warehouses.

Data Warehouse Architecture

The three-tier architecture of a data warehouse is a common design pattern that separates the system into three distinct layers:

Bottom-Tier:The bottom layer, or the data storage layer, stores large amounts of raw data and is optimized for efficient data retrieval. This layer typically consists of relational databases or specialized data storage systems.

Middle-Tier: The middle layer, or the data integration layer, integrates and transforms the raw data from the bottom layer into a format that the top layer can use. This layer includes Extract, Transform, Load (ETL) processes, data cleansing, and data quality checks.

Top-Tier: The top layer, or the data presentation layer, presents the integrated and transformed data to users through reporting, analysis, and data visualization tools. This layer includes OLAP (Online Analytical Processing) cubes, data dashboards, and business intelligence applications.

By separating the data warehouse into these three layers, organizations can optimize each layer for specific tasks and improve the performance and scalability of the system.

By separating the data warehouse into these three layers, organizations can optimize each layer for specific tasks and improve the performance and scalability of the system.

Why Do We Need a Data Warehouse? Advantages:

Improved Data Quality: Data warehouses help improve data quality by standardizing and transforming data from various sources into a consistent format. This can help to reduce errors and improve the accuracy of business decisions.

Centralized Repository: Data warehouses provide a centralized repository for storing and managing data, which makes it easier to access, analyze, and share data across an organization.

Scalability: Data warehouses can be designed to scale as the amount of data grows, making it possible to accommodate increasing amounts of data over time.

Performance: Data warehouses are optimized for fast data retrieval and analysis, allowing organizations to quickly access and analyze large amounts of data to support business decision-making.

Complexity: Data warehouses can be complex to set up and maintain, requiring specialized knowledge and expertise.

Cost: It can be expensive to implement and maintain, particularly for large enterprises with complex data requirements.

Maintenance: It requires ongoing maintenance and management, including regular updates to data, ETL processes, and hardware.

Data Latency: It can introduce latency in the data integration and analysis process, particularly for real-time data needs.

Limited Flexibility: Data warehouses can be inflexible, as they are designed to support specific business requirements and may not be easily adapted to changing needs or requirements.


Organizations must carefully consider their data needs, requirements, and budget when implementing a data warehouse. Sometimes, a data warehouse may not be necessary or cost-effective, and alternative solutions such as data lakes or cloud-based data storage and analysis services may be more appropriate.

Regardless of the specific solution, it is important for organizations to have a clear understanding of their data needs and requirements to make informed decisions about how to manage, store, and analyze their data effectively.
