INTRODUCTION

The Text Analysis Conference (TAC) is a series of evaluations and
workshops organized to promote research in Natural Language Processing
and related applications, by providing a large test collection, common
evaluation procedures, and a forum for organizations to share their
results.

The goal of TAC Knowledge Base Population (KBP) is to develop and
evaluate technologies for building and populating knowledge bases
(KBs) from unstructured text. KBP systems must ultimately build a KB
from scratch, but must also be able to populate an existing reference
KB that has incomplete or unkown provenance.

You are invited to participate in TAC KBP 2014. Organizations may
choose to participate in any or all of the TAC KBP 2014 tracks. NIST
provides test data for each KBP task, and participants run their NLP
systems on the data and return their results to NIST for evaluation.
TAC KBP culminates in a November workshop at NIST in Gaithersburg,
Maryland, USA.

All results submitted to NIST are archived on the TAC web site, and
all evaluations of submitted results are included in the workshop
proceedings. Dissemination of TAC work and results other than in the
workshop proceedings is welcomed, but the conditions of participation
specifically preclude any advertising claims based on TAC results.

TRACKS

1)  Cold Start KBP
http://www.nist.gov/tac/2014/KBP/ColdStart/
The Cold Start track builds a knowledge base from scratch.

2)   Entity Linking
http://nlp.cs.rpi.edu/kbp/2014/
The entity linking task is to discover and link names in a document
collection to entities in a reference KB, or to new named entities
discovered in the document collection.

3)  Slot Filling
http://surdeanu.info/kbp2014/index.php
The slot filling task is to search a document collection to fill in
values for predefined slots (attributes) for a given entity in a
reference KB.

4)  Slot Filler Validation
http://www.nist.gov/tac/2014/KBP/SFValidation/
The Slot Filler Validation track focuses on the refinement of output
from slot filling systems by either combining information from
multiple slot filling systems, or applying more intensive linguistic
processing to validate individual candidate slot fillers.

5)  Sentiment
http://www.nist.gov/tac/2014/KBP/Sentiment/
The goal of the Sentiment track is to assess the quality of detectors
for scoped and attributed sentiment.

6)  Event
http://www.nist.gov/tac/2014/KBP/Event/
The goal of the Event track is to extract information about events
such that the information would be suitable as input to a knowledge
base.

WHAT’S NEW

1) Event track for identifying events from a predefined ontology and
extracting their arguments from text
2) English entity DISCOVERY and linking task
3) Cross-lingual Spanish and Chinese entity linking over discussion forums
3) Multi-document provenance and inference for slot filling and Cold Start KBP
4) Cold Start task variant providing evaluation queries in advance
(similar to slot filling)


REGISTRATION

Organizations wishing to participate in any of the TAC KBP 2014 tracks
are invited to register online by June 15, 2014. Participants are
advised to register and submit all required agreement forms as soon as
possible in order to receive timely access to evaluation resources,
including any sample and training data. Registration for a track does
not commit you to participating in the track, but is helpful to know
for planning. Late registration will be permitted only if resources
allow. Any questions about conference participation may be sent to the
TAC project manager: tac-manager@nist.gov

WORKSHOP

The TAC 2014 workshop will be held November 17-18, 2014, in
Gaithersburg, Maryland, USA. The workshop is a forum both for
presentation of results (including failure analyses and system
comparisons), and for more lengthy system presentations describing
techniques used, experiments run on the data, and other issues of
interest to NLP researchers. KBP track participants who wish to give a
presentation during the workshop will submit a short abstract in
September describing the experiments they performed. As there is a
limited amount of time for oral presentations, the abstracts will be
used to determine which participants are asked to speak and which will
present in a poster session.
