从各种各样的源数据中提取元网络数据可能是困难的，但是使用NetMapper提取和分析这些数据是轻而易举的。NetMapper可以直接输出到ORA Pro进行分析和可视化，使您的工作比以往更容易。NetMapper是一种支持从文本中提取网络，并在上下文层次上分配情感的工具。每个文本被单独处理，并导出该文本的网络表示形式。NetMapper与ORA是可互操作的，给定文本，NetMapper可以提取概念和概念之间的链接，可以快速定制NetMapper来支持提取感兴趣的术语。
NetMapper的输出是CSV格式的，并且是ORA读取的xml格式。NetMapper是基于词典和一个广泛的集词库，翻译文件和删除列表超过40种语言。此外，它还支持使用用户生成的域同义词库和删除列表。因此，在特定领域或特定主题上工作的用户可以使用域文件微调提取的概念。
NetMapper专为网络维护管理者设计的一款多功能网络测试仪表。它可以快速的确认线缆的问题，并且可以显示出整个网络的有用资讯，以供维护人员做快速的维修判断。NETmapper不但可以做离线的线缆检测及在线的线缆检测以及在线的网路资讯采集，同时也可以侦测电话线的电压，并且也具备有类比声频信号产生仪，可以提供寻线功能。此外，它也具备Prot-finder功能。可以辨识终端机相对应的网络连接。

【英文介绍】
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.
