Viglet Turing ES: README

Preface

Viglet Turing ES (https://openviglet.github.io/turing/) is an open source solution (https://github.com/openturing), which has Semantic Navigation and Chat bot as its main features. You can choose from several NLPs to enrich the data. All content is indexed in Solr as search engine.

3. NLP

Turing support the followings providers:

3.1. OpenNLP

Apache OpenNLP is a machine learning based toolkit for the processing of natural language text.

Website: https://opennlp.apache.org/

3.2. OpenText Content Analytics

It transforms data into insights for better decision-making and information management while freeing up resources and time.

Website: https://www.opentext.com/

3.3. CoreNLP

CoreNLP is your one-stop shop for natural language processing in Java! CoreNLP enables users to derive linguistic annotations for text, including token and sentence boundaries, parts of speech, named entities, numeric and time values, dependency and constituency parses, coreference, sentiment, quote attributions, and relations. CoreNLP currently supports 6 languages: Arabic, Chinese, English, French, German, and Spanish.

3.4. SpaCy

It is a free open-source library for Natural Language Processing in Python. It features NER, POS tagging, dependency parsing, word vectors and more.

Website: https://spacy.io

3.5. Polyglot NLP

Polyglot is a natural language pipeline that supports massive multilingual applications.

Website: https://polyglot.readthedocs.io

4. Documents and OCR

It can read PDFs and Documents and convert to plain text, and also it uses OCR to detect text in images and images into documents.

5. Semantic Navigation

5.1. Connectors

Semantic Navigation uses Connectors to index the content from many sources.

5.1.1. Apache Nutch

Plugin for Apache Nutch to index content using crawler.

Learn more at https://docs.viglet.com/turing/connectors/#nutch

5.1.2. Database

Command line that uses the same concept as sqoop (https://sqoop.apache.org/), to create complex queries and map attributes to index based on the result.

Learn more at https://docs.viglet.com/turing/connectors/#database

5.1.3. File System

Command line to index files, extracting text from files such as Word, Excel, PDF, including images, through OCR.

Learn more at https://docs.viglet.com/turing/connectors/#file-system

5.1.4. OpenText WEM Listener

OpenText WEM Listener to publish content to Viglet Turing.

Learn more at https://docs.viglet.com/turing/connectors/#wem

5.1.5. WordPress

WordPress plugin that allows you to index posts.

Learn more at https://docs.viglet.com/turing/connectors/#wordpress

5.2. Named Entity Recognition (NER)

With NLP, it is possible to detect entities such as:

• People

• Places

• Organizations

• Money

• Time

• Percentage

5.3. Facets

Define attributes that will be used as filters for your navigation, consolidating the total content in your display

5.4. Targeting Rules

Through attributes defined in the contents, it is possible to use them to restrict their display based on the user’s profile.

5.5. SDK Java

Java API (https://github.com/openturing/turing-java-sdk) facilitates the use and access to Viglet Turing ES, without the need for consumer search content with complex queries.

6. Chatbot

Communicate with your client and elaborate complex intents, obtain reports and progressively evolve your interaction.

Its components:

6.1. Agent

Handles conversations with your end users. It is a natural language processing module that understands the nuances of human language

6.2. Intent

An intent categorizes an end user’s intention for taking a conversation shift. For each agent, you define several intents, where your combined intents can handle a complete conversation.

6.3. Actions

The field of action is a simple field of convenience that helps to execute logic in the service.

6.4. Entity

Each intent parameter has a type, called an entity type, that dictates exactly how the data in an end user expression is extracted.

6.5. Training

Defines and corrects intents.

6.6. History

Shows the conversation history and reports.

7. OpenText Blazon Integration

Turing ES detects Entities of OpenText Blazon Documents using OCR and NLP, generating Blazon XML to show the entities into document.

8. Turing ES Console

Turing ES has many components: Search Engine, NLP, Converse (Chat bot), Semantic Navigation

8.1. Login

When access the Turing ES, appear a login page. For default the login/password is admin/admin

9. Customer Case Studies

9.1. Insurance Company

On Intranet of Insurance Company uses OpenText WEM and OpenText Portal integrated with Dynamic Portal Module, a consolidated search was created in Viglet Turing ES, using the connectors: WEM, Database with File System. In this way it was possible to display all the contents and files of the search Intranet, with targeting rules, allowing only to display content that the user has permission. The OpenText Portal accesses Viglet Turing ES Java API, so it was not necessary to create complex queries to return the results.

9.2. Government Company

A set of API Rest was created to make all Government Company content available to partners. All these contents are in OpenText WEM and the WEM connector was used to index the contents on Viglet Turing ES. A Spring Boot application was created with the Rest API set that consumes Turing ES content through the Viglet Turing ES Java API.

9.3. Brazilian University

Brazilian University website was developed using Viglet Shio CMS (https://viglet.com/shio), and all contents are indexed in Viglet Turing ES automatically. This configuration was made in content modeling and the development of the search template was made in Viglet Shio CMS.
