Automatically Harvesting Katakana-English Term Pairs from Search Engine Query Logs
نویسندگان
چکیده
This paper describes a method of extracting katakana words and phrases, along with their English counterparts from non-aligned monolingual web search engine query logs. The method employs a trainable edit distance function to find pairs that have a high probability of being equivalent. These pairs can then be used to further bootstrap training of the edit distance function, resulting in improved back-transliteration from katakana to English. In addition, this is an effective method for mining large numbers of katakana strings to enhance a bilingual lexicon. The improved edit distance function and enhanced lexicon can be used for more accurate alignment of bitexts, and for application during runtime MT and multilingual IR.

Automatically Generating Questions from Queries for Community-based Question Answering
This paper proposes a method that automatically generates questions from queries for community-based question answering (cQA) services. Our query-to-question generation model is built upon templates induced from search engine query logs. In detail, we first extract pairs of queries and user-clicked questions from query logs, with which we induce question generation templates. Then, when a new q...
متن کاملParaphrasing with Search Engine Query Logs
This paper proposes a method that extracts paraphrases from search engine query logs. The method first extracts paraphrase query-title pairs based on an assumption that a search query and its corresponding clicked document titles may mean the same thing. It then extracts paraphrase query-query and title-title pairs from the query-title paraphrases with a pivot approach. Paraphrases extracted in...
متن کاملHarvesting Related Entities with a Search Engine
This paper addresses the problem of related entity extraction and focuses on extracting related persons as a case study. The proposed method builds on a search engine. Specifically, we mine candidate related persons for a query person q using q’s search results and the query logs containing q. The acquired candidates are then automatically rated and ranked using a SVM regression model that inve...
متن کاملA Search Engine based on Query Logs and Search Log Analysis at the University of Sunderland
This work describes a variation on the traditional Information Retrieval paradigm, where instead of text documents being indexed according to their content, they are indexed according to the search terms previous users have used in finding them. We determine the effectiveness of this approach by indexing a sample of query logs from the European Library, and describe its usefulness for multiling...
متن کاملWeb searching in Chinese: A study of a search engine in Hong Kong
been conducted on the query logs in search engines that are primarily English-based (e.g., Excite and AltaVista), only a few of them have studied the information-seeking behavior on the Web in non-English languages. In this article, we report the analysis of the search-query logs of a search engine that focused on Chinese. Three months of search-query logs of Timway, a search engine based in Ho...
