In this paper we give an overview of the Knowledge Base Population (KBP) track at TAC 2010. The main goal of KBP is to promote research in discovering facts about entities and expanding a structured knowledge base with this information. A large source collection of newswire and web documents is provided for systems to discover information. Attributes(More)
Knowledge Base Population (KBP) is an evaluation track of the Text Analysis Conference (TAC), a workshop series organized by the National Institute of Standards and Technology (NIST). In 2013, the KBP evaluations included five tasks targeting information extraction and question answering technologies: Entity Linking, Slot Filling, Temporal Slot Filling,(More)
In recent months, LDC has developed a web-based annotation infrastructure centered around a tree model of annotations and a Ruby on Rails application called the LDC User Interface (LUI). The effort aims to centralize all annotation into this single platform, which means annotation is always available remotely, with no more software required than a web(More)
This paper describes a new test collection for passage retrieval from multilingual, informal text. The task being modeled is that of a monolingual English-speaking user who wishes to search discussion forum text in a foreign language. The system retrieves relevant short passages of text and presents them to the user, translated into English. The test(More)
The DARPA BOLT Information Retrieval evaluations target open-domain natural-language queries over a large corpus of informal text in English, Chinese and Egyptian Arabic. We outline the goals of BOLT IR, comparing it with the prior GALE Distillation task. After discussing the properties of the BOLT IR corpus, we provide a detailed description of the query(More)
Content percentages of volatile liquids and fat extractables in 340 samples of ready-to-eat foods were determined gravimetrically. Volatile liquids were determined by drying samples in a microwave oven with a self-contained balance; results were printed out automatically. Fat extractables were extracted from the samples with mixed ethers; extracts were(More)
The 2-chloroethyl esters of 5 fatty acids have been identified in spice and food samples by gas-liquid chromatography-mass spectrometry (GLC/MS). Twenty-four spice samples were analyzed for the 2-chloroethyl esters of fatty acids by AOAC official multiple residues pesticide procedure using GLC with microcoulometric detection. The esters of capric, lauric,(More)
A method was developed for the determination of pentachlorophenol (PCP) in the seals and enamel of Mason lids. After extraction with acidic CH2Cl2 and methylation, the resulting pentachloroanisole was determined by gas-liquid chromatography (GLC) with electron capture detection (EC). Three of the 9 brands of lids examined contained PCP. Levels were as high(More)
