【英文介紹】
NetMapper is a tool that suports extracting networks from texts and assigning sentiment at the context level. Each text is processed separately and a network representation of that text is exported.
NetMapper is interoperable with ORA. Given a text, NetMapper extracts both concepts and links among them. NetMapper can be rapidly customized to support extraction of just terms of interst.
The output from NetMapper is in CSV and in the xml format read by ORA. NetMapper is lexicon based and an extensive set of thesauri, translation files and delete lists in over 40 languages. In addition, it also supports the use of user-generated domain thesauri and delete lists. Hence, users who are working in a specialized area or on a specialized topic can fine tune what concepts are extracted using the domain files.
Input: Types of Texts
Currently, to use NetMapper the user must put each text to be processed into a txt file.Generally, images should be removed. Examples of types of texts include:
● News documents
● Journal articles
● Blog posts
● tweets
NetMapper can accept data in multiple formats:
● US-ASCII
● UTF-8
● UTF-16
● UTF-32
Types of Networks Supported
Two types of networks ca be extracted:semantic networks and meta-networks.The semantic networks are concept to concept networks. From an ORA perspective, all concepts are treated as being of type knowledge.
The meta-networks are concept to concept except.
NetMapper creates networks through link generation. After the thesauri and delete lists are applied then NetMapper extracts the networks by identifying links among concepts. A link is placed between two concepts when they are within the window of operation. The window of operation is defined by either or both number of concepts and syntactic structure (e.g.number of clauses, sentences, or paragraphs). The exist default choices which have been found empirically to lead to the best results for the type of texts being examined. However, the user can choose to change the defaults by sepcifying:
● Window size based on number of words
● Window size based on number of syntactic units
● Whether or not deleted terms are "counted" in defining the size of the window
Finally, NetMapper auto detects language and moves correctly either from left to right up to down, or the reverse. The user may define the languages in the input file(s). This is on a per file basis, however the UI allows for languages selected for a given file to easily be selected for all other files. There is also the option to have languages detection on or off. If off and no languages are selected for a given file, the default is English. If there are languages defined and language detection is enabled, NM will search the file for additional languages and add any to the list of languages to be used that score above a certain threshold.
