Processed Wikipedia SQLite Databases for Wikilite

This dataset provides pre-processed SQLite databases of Wikipedia articles for use with the Wikilite tool. These databases allow you to quickly and efficiently search and access Wikipedia content offline using Wikilite's lexical and semantic search capabilities.

Supported Languages

Currently, the dataset includes databases for the following languages:

• Sardinian (sc)
• Italian (it)
• Spanish (es)
• English (en)
• German (de)

More languages may be added in the future.

Dataset Structure

Each language is stored as a separate compressed file (.db.gz) within the dataset. For example:

• it.db.gz - Italian Wikipedia database (lexical only)
• sc.all-mini.db.gz - Sardinian Wikipedia database (lexical and semantic)

How to Use This Dataset

1. Install Wikilite
   Download a precompiled binary for your operating system from the Wikilite Releases page. Once downloaded, uncompress the binary.

2. Run the --setup Command
   Execute the binary with the --setup option to install a pre-built database. This command will display a list of available databases, allowing you to select and download the one you need, along with the corresponding GGUF model. For example:

   ./wikilite --setup
   

   Note: Databases in the "fts" folder are for full-text search only and do not support semantic search.

3. Run Wikilite with the Installed Database
   After completing the setup, navigate to the directory containing the wikilite binary. Use the following commands to run Wikilite:

   • To start the web interface for browsing and searching:

     ./wikilite --web
     

   • To search via the command line:

     ./wikilite --cli
     

4. Access the Web Interface
   If you started the web server using the --web option, open your browser and go to http://localhost:35248 to access the web interface for browsing and searching the Wikipedia content.

About Wikilite

Wikilite is a tool that provides offline access to Wikipedia content, featuring:

• Fast and Flexible Lexical Searching: Uses FTS5 (Full-Text Search 5) for efficient keyword-based searching.
• Enhanced Semantic Search: Integrates semantic search capabilities, allowing you to find information based on meaning rather than just keywords.
• Offline Access: Enables access to Wikipedia articles without an internet connection.
• Command-Line Interface (CLI): Allows direct searching from the terminal.
• Web Interface (Optional): Provides a user-friendly way to browse and search content.

Semantic Search Details

Wikilite leverages text embeddings for its optional semantic search. This allows you to find results even if your query does not match keywords directly, handling cases like:

• Typos in your search query.
• Different wordings to express the same concept.
• The article uses synonyms or related terms.

Note: To enable semantic search, you'll need a local GGUF model or an OpenAI-compatible remote server and configure Wikilite accordingly. See the Wikilite GitHub repository for more details.
