The Next Generation Information Technologies and Systems (NGITS) series of conferences provides a forum for presenting and discussing the latest advances in information technology. NGITS conferences are international events held in Israel; previous conferences have taken place in 1993, 1995, 1997, 1999, 2002, and 2006. In addition to 14 reviewed papers, the conference featured two keynote lectures and an invited talk by notable experts. The selected papers may be classified roughly in five broad areas: • Middleware and Integration • Modeling • Healthcare/Biomedical • Service and Information Management • Applications NGITS 2009 also included a demonstration session and an industrial track focusing on how to make software development more efficient by cutting expenses with technol- ogy and infrastructures. This event is the culmination of efforts by many talented and dedicated individuals. We are pleased to extend our thanks to the authors of all submitted papers, the mem- bers of the program committee, and the external reviewers. Many thanks are also due to Nilly Schnapp for local organization and logistics, and to Eugeny Myunster for managing the web site and all other technical things. Finally, we are pleased to ac- knowledge the support of our institutional sponsors: The University of Haifa, the Faculty of Social Sciences and the MIS Department at the University of Haifa, the IBM Haifa Research Lab, and the Technion.

In fact, for text process- ing, this belief is factually based. The problem is that most "real world" search appli- cations involve "complex documents", and such applications are far from solved. Complex documents, or less formally, "real world documents", comprise of a mixture of images, text, signatures, tables, logos, water-marks, stamps, etc, and are often avail- able only in scanned hardcopy formats. Search systems for such document collections are currently unavailable. We describe our efforts at building a complex document information processing (CDIP) prototype. This prototype integrates "point solution" (mature) technologies, such as OCR capability, signature matching and handwritten word spotting tech- niques, search and mining approaches, among others, to yield a system capable of searching "real world documents". The described prototype demonstrates the adage that "the whole is greater than the sum of its parts". To evaluate our CDIP prototype as well as to provide an evaluation platform for future CDIP systems, we also introduced a complex document benchmark. This benchmark is currently in use by the National Institute of Standards and Technology (NIST) Text REtrieval Conference (TREC) Legal Track. The details of our complex document benchmark are similarly presented. Having described the global approach, we describe some additional point solutions developed in the IIT Information Retrieval Laboratory. These include an Arabic stem- mer and a natural language source integration fabric called the Intranet Mediator. In terms of stemming, we developed and commercially licensed an Arabic stemmer and search system. Our approach was evaluated using benchmark Arabic collections and favorably compared against the state of the art. We also focused on source integration and ease of user interaction. By integrating structured and unstructured sources, we de- signed, implemented, and commercially licensed our mediator technology that provides a single, natural language interface to querying distributed sources. Rather than providing a set of links as possible answers, the described approach actually answers the posed question. Both the Arabic stemmer and the mediator efforts are likewise discussed. A summary of the efforts discussed is found in [1]. Reference 1. Frieder, O.: On Searching in the ‘Real World’. In: Argamon, S., Howard, N. (eds.) Com- putational Methods for Counterterrorism, ch. 1.

Halevy Google Inc., 1600 AmphitheatreParkway, Mountain View, California, 94043, USA [email protected] Abstract of Plenary Talk Though search on the World-Wide Web has focused mostly on unstructured text, there is an increasing amount of structured data on the Web and growing interest in harnessing such data. I will describe several current projects at Google whose overall goal is to leverage structured data and betterexpose it to our users. The first project is on crawling the deep web. The deep web refers to content that resides in databases behindforms, but is unreachable bysearch engines because there are nolinks tothese pages. I will describe asystem that surfaces pages from thedeep web by guessing queries to submit to these forms, and entering the results into the Google index [1]. The pages that we generated using this system come from millions of forms, hundreds of domains and over 40 languages. Pages from the deep web are served in thetop-10 results on google.com for over1000 queriesper second. ThesecondprojectconsidersthecollectionofHTMLtablesontheweb.TheWebTa- bles Project [2] built a corpus of over 150 million tables from HTML tables on the Web. The WebTables System addresses the challenges of extracting these tables from theWeb,andofferssearchoverthiscollectionoftables.Theprojectalsoillustratesthe potential of leveraging the collection of schemas of these tables. Finally, I’ll discuss currentwork on computingaspects of queriesin orderto better organize search results for exploratory queries.
