We are happy to announce the inaugural New York Metro Database/Information Retrieval (DB/IR) Day.  We hope that this is the first in a regular series of New York Metro DB/IR Days. 

The New York Metro DB/IR Day will bring together database and information retrieval researchers and students from academic and research institutions across the Greater New York area for an exciting workshop technical program as well as informal discussion. The DB/IR workshops will provide a regular forum for presenting diverse viewpoints on database systems and information retrieval, addressing current topics as well as promoting information exchange among researchers.

The first DB/IR Day will be hosted by Columbia University on April 15, 2005. The program will consist of three technical keynote lectures from distinguished researchers in databases and information retrieval (Alon Halevy, Craig Nevill-Manning and Michael Stonebraker). In addition, we are organizing a student poster session to promote awareness of current DB&IR research at various graduate departments in the North-East area, and stimulate collaborations between academia and industry. Prizes will be awarded for the best posters! 

DB/IR Day will conclude in time for everyone to enjoy an evening in New York City.

Here is the first DB/IR day exciting agenda:

Semex: a Platform for Personal Information Management and Integration

Alon Halevy, Computer Science and Engineering Department, University of Washington

Abstract

The explosion of information available in digital form has made search a hot research topic for the Information Management Community. While most of the research on search is focused on the WWW, individual computer users have developed their own vast collections of data on their desktops, and these collections are in critical need for good search and query tools. The problem is exacerbated by the proliferation of varied electronic devices (laptops, PDAs, cellphones) that are at our disposal, that often hold subsets or variations of our data.

I will argue that Personal Information Management (PIM) poses a key challenge to our community and raises several exciting technical problems. In particular, PIM highlights some of the challenges involved in combining data management and information retrieval technologies.

I will demonstrate the vision of PIM and the associated problems with the Semex System that we are building at the University of Washington. Semex has two main goals. The first goal is to enable browsing and searching personal information by semantically meaningful associations, in the spirit of the Memex vision. The challenge to enabling such browsing and search is to automatically create such associations between data items on one's desktop, and to create enough of them so Semex becomes an indispensable tool. Our second goal is to leverage the personal information space we created to increase users' productivity. As our first target, Semex leverages the personal information to enable lightweight information integration tasks that are discouragingly difficult to perform with today's tools.

This is joint work with Luna Dong and Jayant Madhavan.

Neither fish nor fowl - between relations and bags of words

Craig Nevill-Manning, Director, New York Engineering & Senior Staff Research Scientist, Google Inc.

Abstract

Search engines like Google help users to sift unstructured documents, treating them largely as bags of words. Relational databases allow retrieval using complex, precise queries. But there's a large amount of data that falls between the two extremes -- databases that are presented as documents (e.g. an Amazon product page), and documents that contain structured data (e.g. the address and phone number on your home page.) This information is not sufficiently structured to permit relational indexing and searching, but treating it as a bag of words loses valuable information. Furthermore, it's difficult to design schemas for everything in the world, so a relational model is too restrictive. Google is currently wrestling with these issues: Froogle uses dynamic programming to extract structured information about products, and allows users to query products on various attributes.

Google Local scours the web for geographical references, and combines these with structured data from yellow pages. Google Scholar reconstructs a citation graph by extracting title and author information from the first page and references of academic publications. I'll give some background on these problems, describe the way we approach them at Google, and discuss the impact that solutions will have on the way people access and use information.

One Size Fits All: An Idea Whose Time Has Come and Gone

Michael Stonebraker, Computer Science and Artificial Intelligence Laboratory, M.I.T., and StreamBase Systems, Inc.

Abstract

The last 25 years of commercial DBMS development can be summed up in a single phrase: One size fits all. This phrase refers to the fact that the traditional DBMS architecture (originally designed and optimized for business data processing) has been used to support many data-centric applications with widely varying characteristics and requirements.

In this talk, we argue that this concept is no longer applicable to the database market, and that the commercial world will fracture into a collection of independent database engines, some of which may be unified by a common front-end parser. We use examples from the stream-processing market and the data-warehouse market to bolster our claims. We also briefly discuss other markets for which the traditional architecture is a poor fit and argue for a critical rethinking of the current factoring of systems services into products.
