MSR Identity Toolbox: A Matlab Toolbox for Speaker Recognition Research Version 1.0 Seyed Omid Sadjadi, Malcolm Slaney, and Larry Heck Microsoft Research, Conversational Systems Research Center (CSRC) s.omid.sadjadi@gmail.com, {mslaney,larry.heck}@microsoft.com This report serves as a user manual for the tools available in the Microsoft Research (MSR) Identity Toolbox. This toolbox contains a collection of Matlab tools and routines that can be used for research and development in speaker recognition. It provides researchers with a test bed for developing new front-end and back-end techniques, allowing replicable evaluation of new advancements. It will also help newcomers in the field by lowering the “barrier to entry”, enabling them to quickly build baseline systems for their experiments. Although the focus of this toolbox is on speaker recognition, it can also be used for other speech related applications such as language, dialect and accent identification. In recent years, the design of robust and effective speaker recognition algorithms has attracted significant research effort from academic and commercial institutions. Speaker recognition has evolved substantially over the past 40 years; from discrete vector quantization (VQ) based systems to adapted Gaussian mixture model (GMM) solutions, and more recently to factor analysis based Eigenvoice (i-vector) frameworks. The Identity Toolbox provides tools that implement both the conventional GMM-UBM and state-of-the-art i-vector based speaker recognition strategies. A speaker recognition system includes two primary components: a front-end and a back-end. The front-end transforms acoustic waveforms into more compact and less redundant representations called acoustic features. Cepstral features are most often used for speaker recognition. It is practical to only retain the high signal-to-noise ratio (SNR) regions of the waveform, therefore there is also a need for a speech activity detector (SAD) in the fr

Bochs - The cross platform IA-32 (x86) emulator

Chinese Entity Linking Comprehensive

TAC KBP Chinese Entity Linking Comprehensive Training and Evaluation Data 2011-2014 LDC2015E17 March 20, 2015 Linguistic Data Consortium 1. Overview Text Analysis Conference (TAC) is a series of workshops organized by the National Institute of Standards and Technology (NIST). TAC was developed to encourage research in natural language processing (NLP) and related applications by providing a large test collection, common evaluation procedures, and a forum for researchers to share their results. Through its various evaluations, the Knowledge Base Population (KBP) track of TAC encourages the development of systems that can match entities mentioned in natural texts with those appearing in a knowledge base and extract novel information about entities from a document collection and add it to a new or existing knowledge base. The goal of Entity Linking is to determine whether or not the entity referred to in each query has a matching entity node in the reference Knowledge Base (KB) (LDC2014T16). If there is a matching node for a query, annotators create a link between the two. If there is not a matching node for a query, the entity is marked as 'NIL' and then clustered with other NIL entities into equivalence classes. For more information, please refer to the Entity Linking section of NIST's 2014 TAC KBP website (2014 was the last year in which the Chinese Entity Linking evaluation was conducted as of the time this package was created) at http://nlp.cs.rpi.edu/kbp/2014/ This package contains all evaluation and training data developed in support of TAC KBP Chinese Entity Linking during the four years since the task's inception in 2011. This includes queries, KB links, equivalence class clusters for NIL entities (those that could not be linked to an entity in the knowledge base), and entity type information for each of the queries. The data included in this package were originally released by LDC to TAC KBP coordinators and performers under the following ecorpora catalog IDs and titles: LDC2011E46: TAC 2011 KBP Cross-lingual Sample Entity Linking Queries V1.1 LDC2011E55: TAC 2011 KBP Cross-lingual Training Entity Linking V1.1 LDC2012E34: TAC 2011 KBP Cross-Lingual Evaluation Entity Linking Annotation LDC2012E66: TAC 2012 KBP Chinese Entity Linking Web Training Queries and Annotations LDC2012E103: TAC 2012 KBP Chinese Entity Linking Evaluation Annotations V1.2 LDC2013E96: TAC 2013 KBP Chinese Entity Linking Evaluation Queries and Knowledge Base Links V1.2 LDC2014E47: TAC 2014 KBP Chinese Entity Linking Discussion Forum Training Data LDC2014E83: TAC 2014 KBP Chinese Entity Linking Evaluation Queries and Knowledge Base Links V2.0 2.

Annotation Given a name string and using information from the query's source document, bilingual Chinese/English-speaking annotators used a specialized search engine to look in the Knowledge Base for a page in which the entity referred to by the query was the central topic. If such a page was found, a link was created between the query and the matching KB node ID. If no matching page was found, the query was marked as NIL and later coreferenced with other NIL entities. Annotators were allowed to use online searching to assist in determining the KB link/NIL status. Queries for which a human annotator could not confidently determine the KB link status were removed from the final data sets. 4. Text Normalization Name string matches are case and punctuation sensitive. The only text normalization performed was: 1. conversion of newlines to spaces, except where preceding characters were hyphens ("-"), in which case newlines were removed 2. conversion of multiple spaces to a single space 5. Source Documents All the text data in the source files have been taken directly from previous LDC corpus releases, and are being provided here essentially "as-is", with little or no additional quality control. An overall scan of character content in the source collections indicates some relatively small quantities of various problems, especially in the web and discussion forum data, including language mismatch (characters from Chinese, Korean, Japanese, Arabic, Russian, etc.), and encoding errors (some documents have apparently undergone "double encoding" into UTF-8, and others may have been "noisy" to begin with, or may have gone through an improper encoding conversion, yielding occurrences of the Unicode "replacement character" (U+FFFD) throughout the corpus); the web collection also has characters whose Unicode code points lie outside the "Basic Multilanguage Plane" (BMP), i.e. above U+FFFF. All documents that have filenames beginning with "cmn-NG" and "eng-NG" are Web Document data (WB) and some of these fail XML parsing (see below for details). All files that start with "bolt-" are Discussion Forum threads (DF) and have the XML structure described below. All other files are Newswire data (NW) and have the newswire markup pattern detailed below. Note as well that some source documents are duplicated across a few of the separated source_documents directories, indicating that some queries from different data sets originated from the same source documents. As it is acceptable for sources to be reused for Entity Linking queries, this duplication is intentional and expected. The subsections below go into more detail regarding the markup and other properties of the three source data types: 5.1 Newswire Data Newswire data use the following markup framework: <DOC id="{doc_id_string}" type="{doc_type_label}"> <HEADLINE> ... </HEADLINE> <DATELINE> ... </DATELINE> <TEXT> <P> ... </P> ... </TEXT> </DOC> where the HEADLINE and DATELINE tags are optional (not always present), and the TEXT content may or may not include "<P> ... </P>" tags (depending on whether or not the "doc_type_label" is "story"). All the newswire files are parseable as XML. 5.2 Discussion Forum Data Discussion forum files use the following markup framework: <doc id="{doc_id_string}"> <headline> ... </headline> <post ...> ... <quote ...> ... </quote> ... </post> ... </doc> where there may be arbitrarily deep nesting of quote elements, and other elements may be present (e.g. "<a...>...</a>" anchor tags). As mentioned in section 2 above, each <doc> unit contains at least five post elements. All the discussion forum files are parseable as XML. 5.3 Web Document Data "Web" files use the following markup framework: <DOC> <DOCID> {doc_id_string} </DOCID> <DOCTYPE> ... </DOCTYPE> <DATETIME> ... </DATETIME> <BODY> <HEADLINE> ... </HEADLINE> <TEXT> <POST> <POSTER> ... </POSTER> <POSTDATE> ... </POSTDATE> ... </POST> </TEXT> </BODY> </DOC> Other kinds of tags may be present ("<QUOTE ...>", "<A >", etc). Some of the web source documents contain material that interferes with XML parsing (e.g. unescaped "&", or "<QUOTE>" tags that lack a corresponding "</QUOTE>"). 6. Using the Data 6.1 Offset calculation The values of the beg and end XML elements in the later queries.xml files indicate character offsets to identify text extents in the source. Offset counting starts from the initial character (character 0) of the source document and includes newlines and all markup characters - that is, the offsets are based on treating the source document file as "raw text", with all its markup included. 6.2 Proper ingesting of XML queries While the character offsets are calculated based on treating the source document as "raw text", the "name" strings being referenced by the queries sometimes contain XML metacharacters, and these had to be "re-escaped" for proper inclusion in the queries.xml file. For example, an actual name like "AT&T" may show up a source document file as "AT&T" (because the source document was originally formatted as XML data). But since the source doc is being treated here as raw text, this name string is treated in queries.xml as having 7 characters (i.e., the character offsets, when provided, will point to a string of length 7). However, the "name" element itself, as presented in the queries.xml file, will be even longer - "AT&amp;T" - because the queries.xml file is intended to be handled by an XML parser, which will return "AT&T" when this "name" element is extracted. Using the queries.xml data without XML parsing would yield a mismatch between the "name" value and the corresponding string in the source data. 7.
