php semantic search
1.0.0
Estas clases contienen interfaces para la búsqueda e implementaciones semánticas para ellos utilizando Ropherta como Búsqueda de vectores SQLITE y SQLITE3 como Base de datos vectorial. También se proporciona una búsqueda de palabras clave utilizando SQLITE3 FTS4 y BM25.
Para completar la base de datos de vector, la clase Ingester contiene un frasco recursivo similar al disponible en Langchain, pero con algunas velocidades más la capacidad de referirse a las compensaciones en el documento de origen.
Los usos más avanzados incluyen el uso de Vector Search como Reranker y usar HYDE para obtener incrustaciones simétricas.
Una fuente de demostración documenta e indexa más de 35,000 documentos de la documentación de StackOverflow y PHP está disponible para descargar.
El componente de ingestión toma documentos en formato JSONL , con un documento JSON bien formado por línea.
El texto debe ser texto plano UTF-8 codificado (por especificación JSON). El sistema lo dividirá en trozos en la ingestión.
{ "url": "...", "title": "...", "text": "...", "section": "...", "license": "..." }
Necesita instalado SQLite-VSS (tanto Vector0 como Vss0.SO)

composer exec -- php -r "require 'vendor/autoload.php'; OnnxRuntimeVendor::check();"
Si desea utilizar el modelo multilingüe, no descargue este modelo y siga las instrucciones en la siguiente sección. Para el modelo en inglés, descargue la oración del modelo Roberta Onnx (esto lleva un tiempo, el modelo tiene un tamaño de 362 MB):
composer exec -- php -r "require 'vendor/autoload.php'; TextualizationSentenceTransphormersVendor::check();"
Descargue la biblioteca de la pieza de oración:
composer exec -- php -r "require 'vendor/autoload.php'; TextualizationSentencePieceVendor::check();"
Descargue el modelo XLM Tokenizer SentencePiece BPE:
composer exec -- php -r "require 'vendor/autoload.php'; TextualizationRophertaTokenizerVendor::check();"
Descargue el modelo multilingüe-e5-small (de 471 MB de tamaño):
composer exec -- php -r "require 'vendor/autoload.php'; TextualizationSentenceTransphormersVendor::check(true);"
Tenga en cuenta: si ha descargado el modelo inglés, primero necesitará eliminarlo. Actualmente solo es posible un modelo, esta limitación se elevará en futuras versiones.
Instale la extensión SQLITE3 y Ropherta según las instrucciones anteriores.
Descargue los datos e índices de http://textualization.com/download/phpsemsearch_0.1.tar.bz2 (192mb).
Descomprima y mueva los archivos vector.db y keyword.db a la carpeta raíz.
Los principales documentos parecen bastante aptos.

La búsqueda vectorial utilizando un incrustador simétrico (como la oración Roberta) funciona mejor cuando se busca documentos similares que no consulten contra documentos. Para tales casos, Hyde (presentado a continuación) es mejor. Alternativos, los embebidos asimétricos (como el instructor) se pueden transportar a PHP a través de ONNX.

Se puede pasar a través de un archivo, una variable de entorno o directamente en el constructor. Tenga en cuenta que llamar a OpenAi es muy lento . En este ejemplo, el texto de ChatGPT arroja la búsqueda vectorial a algunas direcciones que no son necesariamente ideales. Un texto más corto podría haber sido mejor.

Hdydrated query: There are several ways to prevent Composer from timing out during script execution:
1. Increase the timeout limit: By default, Composer has a timeout limit of 300 seconds (5 minutes). You can increase this limit by modifying the ` max_execution_time ` directive in your PHP configuration file (php.ini). Set it to a higher value, such as 600 (10 minutes) or more, depending on your script ' s requirements.
2. Optimize your script: If your script is taking too long to execute, consider optimizing it to reduce the execution time. Analyze your code and identify any bottlenecks or areas that can be improved. Use efficient algorithms, avoid unnecessary loops or recursive calls, and optimize database queries if applicable.
3. Split your script into smaller tasks: If your script performs multiple tasks, consider breaking it down into smaller tasks and executing them separately. This way, you can avoid hitting the timeout limit by completing each task within the allowed time frame.
4. Use command-line execution: Instead of running the script through a web server, you can execute it via the command line. Command-line execution typically has a longer timeout limit compared to web server execution. You can run the script using the `php` command followed by the script ' s file path.
5. Increase memory limit: If your script requires more memory to execute, you can increase the memory limit in your PHP configuration file (php.ini). Modify the ` memory_limit ` directive and set it to a higher value, such as 256M or more, depending on your script ' s memory requirements.
6. Use caching: If your script performs repetitive or resource-intensive tasks, consider implementing caching mechanisms. Caching can help reduce the execution time by storing and retrieving precomputed or frequently accessed data instead of recalculating it every time.
7. Use asynchronous processing: If your script involves time-consuming operations, consider using asynchronous processing techniques. Instead of waiting for each operation to complete before moving to the next, you can execute them concurrently or in the background using tools like queues, workers, or event-driven architectures.
Remember to restart your web server or PHP service after making changes to the PHP configuration file for the changes to take effect.

<p>I thought it might help to add some more specific details of a specific situation here. Consider that there is a 'Preview' page. Now when I submit the input from a textarea, the Preview page receives the input and shows it html and at the same time, a hidden input collects this input. When the submit button on the Preview button is hit, then the data from the hidden input is POST'ed to a new page and that page inserts the data contained in the hidden input, into the DB. If I do not apply htmlentities when the form is initially submitted (but apply only strip_tags and mysql_real_escape_string) and there's a malicious input in the textarea, the hidden input is broken and the last few characters of the hidden input visibly seen as <code>" /></code> on the page, which is undesirable. So keeping this in mind, I need to do something to preserve the integrity of the hidden input properly on the Preview page and yet collect the data in the hidden input so that it does not break it. How do I go about this? Apologize for the delay in posting this info.</p>Tenga en cuenta que el índice de palabras clave no se tritura (todos los números de fragmentos son 0).

Un archivo de muestra está disponible para la descarga.
$ composer run-script index keyword sophp.jsonl$ composer run-script index vector sophp.jsonlPara usar un índice reiniciado, cree un vector y índices de palabras clave por separado.
La indexación de vectores toma aproximadamente un día y consume una cantidad significativa de RAM en este momento.
El chunker recursivo se puede usar independiente:
$ composer run-script chunk ropherta null 1024 tests/sornd1000.jsonl output.jsonl Los documentos de salida JSONL tienen claves:
title )text )url )chunk_num )offset_start )offset_end )license ) Otros tokenizadores son posibles, vea el código en la carpeta scripts . El uso de la cadena null (nulo) establece el tamaño en caracteres en lugar de tokens.
$ composer run-script embed /path/to/model.onnx " actual text to compute embeddings " Para expandir las respuestas utilizando un servicio de finalización (como Open AI CHATGPT) Use:
$ composer run-script hydrate /path/to/open-ai-key 1024 tests/sornd1000.jsonl output.jsonl Pobles la completion del campo del title en el objeto JSON .
