The objective of this paper is to give a comprehensive introduction to applied cryptography with an engineer or computer scientist in mind. The emphasis is on the knowledge needed to create practical systems which supports integrity, confidentiality, or authenticity. Topics covered includes an introduction to the concepts in cryptography, attacks against cryptographic systems, key use and handling, random bit generation, encryption modes, and message authentication codes. Recommendations on algorithms and further reading is given in the end of the paper. This paper should make the reader able to build, understand and evaluate system descriptions and designs based on the cryptographic components described in the paper.

KEY BENEFIT: Written by a leader in the field of information retrieval, this text provides the background and tools needed to evaluate, compare and modify search engines. KEY TOPICS: Coverage of the underlying IR and mathematical models reinforce key concepts. Numerous programming exercises make extensive use of Galago, a Java-based open source search engine. MARKET: A valuable tool for search engine and information retrieval professionals.

Search Engines: Information Retrieval in Practice

It has now been 50 years since the publication of Luhn’s seminal paper on automatic summarization. During these years the practical need for automatic summarization has become increasingly urgent and numerous papers have been published on the topic. As a result, it has become harder to find a single reference that gives an overview of past efforts or a complete view of summarization tasks and necessary system components. This article attempts to fill this void by providing a comprehensive overview of research in summarization, including the more traditional efforts in sentence extraction as well as the most novel recent approaches for determining important content, for domain and genre specific summarization and for evaluation of summarization. We also discuss the challenges that remain open, in particular the need for language generation and deeper semantic understanding of language that would be necessary for future advances in the field. We would like to thank the anonymous reviewers, our students and Noemie Elhadad, Hongyan Jing, Julia Hirschberg, Annie Louis, Smaranda Muresan and Dragomir Radev for their helpful feedback.

Automatic Summarization

A system and method to facilitate classification and storage of events in a network are described. An event and associated content information are received from an entity over a network. The content information is further analyzed to determine one or more themes representing subject matter related to the content information. The event is further classified according to the themes into one or more corresponding categories. Finally, the event is stored into one or more corresponding databases of a data storage module according to the one or more corresponding categories.

A system and method to facilitate classification of search queries and selection of associated advertising information over a network are described. A search query received from a user over a network is processed to retrieve a predetermined number of query results. The predetermined number of query results is further classified to select one or more categories associated with the query results. Finally, advertising information is selected based on the one or more selected categories for further display to the user in connection with the query results.

Although object-oriented software development has experienced the benefits of using frameworks, a thorough understanding of how to change them to meet evolving requirement needs is still object of research. Therefore framework development is very expensive, not only because of the intrinsic difficulty related to capturing the domain theory, but also because of the lack of appropriate methods and techniques to support the evolution and redesign of the framework architecture. This paper proposes the use of refactoring and unification rules to assist framework evolution. The approach is illustrated through the JUnit testing framework.

Using refactoring and unification rules to assist framework evolution

Provided are a system and article of manufacture for searching documents for ranges of numeric values. Document identifiers for documents include at least one value that is a member of a set of values. A number of posting lists is generated, wherein each posting list is associated with a range of consecutive values within the set of values and includes document identifiers for documents including at least one value within the range of consecutive values associated with the posting list, and wherein each document identifier is associated with one value in the set of values included in the document identified by the document identifier. The generated posting lists are stored, wherein the posting lists are used to process a query on a range of values within the set of values. A query on a query range of values within the set of values is received and a determination is made of a minimum number of posting lists associated with consecutive values that together include the query range of values. The determined posting lists are merged to form a merged posting list including document identifiers of documents including values within the query range. The document identifiers in the merged posting list are returned.

A system and method to facilitate mapping and storage of data within one or more data taxonomies are described. Content information is received over a network. The content information is further analyzed to determine at least one theme representing subject matter related to the content information. Finally, the content information is stored within respective predetermined categories organized within at least one taxonomy, the predetermined categories being associated with the at least one theme.
