We present Wikulu1 , a system focusing on supporting wiki users with their everyday tasks by means of an intelligent interface. Wikulu is implemented as an extensible architecture which transparently integrates natural language processing (NLP) techniques with wikis. It is designed to be deployed with any wiki platform, and the current prototype integrates a wide range of NLP algorithms such as keyphrase extraction, link discovery, text segmentation, summarization, or text similarity. | Wikulu An Extensible Architecture for Integrating Natural Language Processing Techniques with Wikis Daniel Bar Nicolai Erbs Torsten Zesch and Iryna Gurevych Ubiquitous Knowledge Processing Lab Computer Science Department Technische Universitat Darmstadt Hochschulstrasse 10 D-64289 Darmstadt Germany Abstract We present Wikultk a system focusing on supporting wiki users with their everyday tasks by means of an intelligent interface. Wikulu is implemented as an extensible architecture which transparently integrates natural language processing NLP techniques with wikis. It is designed to be deployed with any wiki platform and the current prototype integrates a wide range of NLP algorithms such as keyphrase extraction link discovery text segmentation summarization or text similarity. Additionally we show how Wikulu can be applied for visually analyzing the results of NLP algorithms educational purposes and enabling semantic wikis. 1 Introduction Wikis are web-based collaborative content authoring systems Leuf and Cunningham 2001 . As they offer fast and simple means for adding and editing content they are used for various purposes such as creating encyclopedias . Wikipedia 2 3 constructing dictionaries . Wiktionary2 or hosting online communities . ACLWiki4 . However as wikis do not enforce their users to structure pages or add complementary metadata wikis often end up as a mass of unmanageable pages with meaningless page titles and no usable link structure Buffa 2006 . To solve this issue we present the Wikulu system which uses natural language processing to support wiki users with their typical tasks of adding Portmanteau of the Hawaiian terms wiki fast and kukulu to organize 2http 3http 4http aclwiki 74 organizing and finding content. For example Wikulu supports users with reading longer texts by highlighting keyphrases using keyphrase extraction methods such as TextRank Mihalcea and .
