Multi-Document Summarization By Sentence Extraction

by Jade Goldstein Vibhu Mittal, Jade Goldstein, Vibhu Mittal, Jaime Carbonell, Mark Kantrowitz - In Proceedings of the ANLP/NAACL Workshop on Automatic Summarization , 2000
"... This paper discusses a text extraction approach to multidocument summarization that builds on single-document summarization methods by using additional, available in-i formation about the document set as a whole and the relationships between the documents. Multi-document summarization differs from ..."

Geographic Reference Analysis for Geographic Document Querying

by Frdrik Bilhaut Thierry, Thierry Charnois, Patrice Enjalbert, Yann Mathet - In Proceedings of Workshop on the Analysis of Geographic References, Human Language Technology Conference (NAACL-HLT , 2003
"... Retrieval from geographical documents, i.e. documents with a major geographic component. The final aim, in response to an informational query of the user, is to return a ranked list of relevant passages in selected documents, allowing text browsing within them. We consider in this paper the spatial ..."

From Cases to Documents to Passages.

by Jody J. Daniels
"... We present the SPIRE system, a hybrid casebased reasoning (CBR) and information retrieval (IR) system. It relies on a small case-base to seed the IR system to 1) select documents that are relevant to a presented problem case, and then (2) highlight within these retrieved documents passages tha ..."

Experiments with Geographic Evidence Extracted from Documents

by Nuno Cardoso, Patrícia Sousa, Mário J. Silva
"... Abstract. For the 2008 participation at GeoCLEF, we focused on improving the extraction of geographic signatures from documents and optimising their use for GIR. The results show that the detection of explicit geographic named entities for including their terms in a tuned weighted index field signif ..."

Creating and Evaluating Multi-Document Sentence Extract Summaries

by Jade Goldstein, Vibhu Mittal, Jaime Carbonell, Jamie Callan - In International Conference on Information and Knowledge Management (CIKM , 2000

This paper discusses passage extraction approaches to multidocument summarization that use available information about the document set as a whole and the relationships between the documents to build on single document summarization methodology. Multi-document summarization differs from single in t ..."

Answer Extraction

by Steven Abney, Michael Collins, Amit Singhal - In Proceedings of ANLP 2000 , 2000
"... Information retrieval systems have typically concentrated on retrieving a set of documents which are relevant to a user's query. This paper describes a system that attempts to retrieve a much smaller section of text, namely, a direct answer to a user's question. The SMART IR system is used ..."

is used to extract a ranked set of passages that are relevant to the query. Entities are extracted from these passages as potential answers to the question, and ranked for plausibility according to how well their type matches the query, and according to their frequency and position in the passages

TextFinder: An Automatic System To Detect And Recognize Text In Images

by Victor Wu, Victor Wu, R. Manmatha, R. Manmatha, Edward M. Riseman, Edward M. Riseman , 1997
"... There are many applications in which the automatic detection and recognition of text embedded in images is useful. These applications include digital libraries, multimedia systems, Information Retrievial Systems, and Geographical Information Systems. When machine generated text is printed against cl ..."

certificates. Current document segmentation and recognition technologies cannot handle these situations well. In this paper, a four-step system which automatically detects and extracts text in images is proposed. First, a texture segmentation scheme is used to focus attention on regions where text may occur

GIPSY: Automated Geographic Indexing of Text Documents

by Allison Gyle Woodruff, Christian Plaunt , 1994
"... In this paper we present an algorithm which automatically extracts geopositional coordinate index terms from text to support georeferenced document indexing and retrieval. Under this algorithm, words and phrases containing geographic place names or characteristics are extracted from a text docume ..."

Using Passage Level Retrieval to Aid Information Extraction

by Jonathan H. Aseltine , 1999
"... This paper explores both how and whether passage level retrieval (PLR) can improve information extraction performance. PLR divides a document into smaller passages, treating each as a single document for retrieval. Queries are then formulated to retrieve passages relevant to a concept. PLR could add ..."

Adding Geographic Scopes to Web Resources

by Mário J. Silva, Bruno Martins, Marcirio Chaves, Ana Paula Afonso, Nuno Cardoso - CEUS - Computers, Environment and Urban Systems , 2006
"... Many Web pages are rich in geographic information and primarily relevant to geographically limited communities. However, existing IR systems only recently began to offer local services and largely ignore geo-spatial information. This paper presents our work on automatically identifying the geographi ..."

Our approach makes extensive use of an ontology of geographical concepts, and includes a system architecture for extracting geographic information from large
