php semantic search

PHP語義搜索課程

該類包含用於語義搜索的接口，並使用ropherta作為嵌入式和sqlite3向量搜索作為矢量數據庫。還提供了使用SQLITE3 FTS4和BM25的關鍵字搜索。

為了填充矢量數據庫， Ingester類包含一個類似於Langchain中可用的遞歸塊，但具有一些速度，並能夠將其引用到源文檔中的偏移。

更高級的用途包括使用向量搜索作為Reranker和使用Hyde獲得對稱嵌入。

可以下載來自Stackoverflow和PHP文檔的35,000個文檔的演示源文檔和索引。

攝取的文檔格式

攝入組件採用JSONL格式的文檔，每行有一個良好的JSON文檔。

該文本應為純文本UTF-8編碼（PER JSON SPEC）。該系統將在攝入時將其分成部分。

 { "url": "...", "title": "...", "text": "...", "section": "...", "license": "..." }

矢量指數下降

您需要安裝sqlite-vss（vector0和vss0.so）

php.ini

放

 [sqlite3]
; Directory pointing to SQLite3 extensions
; https://php.net/sqlite3.extension-dir
sqlite3.extension_dir = /path/to/the/sqlite3-vss-dlls

SQLITE3-VSS依賴項

apt install libgomp1 libblas3 liblapack3

ropherta依賴性

安裝ONNX框架：

 composer exec -- php -r "require 'vendor/autoload.php'; OnnxRuntimeVendor::check();"

如果您想使用多語言模型，請不要下載此模型，並按照下一節中的說明進行操作。對於英語模型，下載句子Roberta ONNX模型（這需要一段時間，該模型的大小為362MB）：

 composer exec -- php -r "require 'vendor/autoload.php'; TextualizationSentenceTransphormersVendor::check();"

多語言模型

下載句子庫：

 composer exec -- php -r "require 'vendor/autoload.php'; TextualizationSentencePieceVendor::check();"

下載XLM Tokenizer句子BPE模型：

 composer exec -- php -r "require 'vendor/autoload.php'; TextualizationRophertaTokenizerVendor::check();"

下載多語言 - E5-small型號（尺寸為471MB）：

 composer exec -- php -r "require 'vendor/autoload.php'; TextualizationSentenceTransphormersVendor::check(true);"

請注意：如果您已經下載了英文型號，則需要先刪除它。目前只有一個模型，將在以後的版本中取消此限制。

例子

根據上述說明安裝SQLite3擴展名和Ropherta。

從http://textualization.com/download/phpsemsearch_0.1.1.tar.bz2（192MB）下載數據和索引。

解壓縮並將文件vector.db和keyword.db移至根文件夾。

關鍵字搜索

頂級文檔似乎很貼切。

向量搜索

不如關鍵字好，但結果確實不同。當搜索類似文檔而不是針對文檔查詢時，使用對稱嵌入器（例如Roberta）使用對稱嵌入器（例如Roberta）進行矢量搜索更好。對於這種情況，海德（下面介紹）更好。替代性，不對稱嵌入式（如講師）可以通過ONNX移植到PHP。

海德

使用此功能需要OpenAI API密鑰。它可以通過文件，環境變量或直接在構造函數中傳遞。請注意，致電Openai非常慢。在此示例中，ChatGPT文本將矢量搜索投入了一些不一定理想的方向。較短的文本可能會更好。

$ composer run-script query ' {"class": "\Textualization\SemanticSearch\VectorHydeIndex", "completion":{"open_ai_key":"/path/to/key"}} ' " How to stop composer giving a time-out on a script execution " 
> Composer C onfig::disableProcessTimeout
> @php scripts/query.php ' {"class": "\Textualization\SemanticSearch\VectorHydeIndex", "completion":{"open_ai_key":"/path/to/key"}} ' ' How to stop composer giving a time-out on a script execution '
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.

Title: PHP & mySQL: When exactly to use htmlentities ?

Text:
 <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>" /&gt;</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>

請注意，關鍵字索引未封鎖（所有塊號為0）。

索引文件

這些文檔以本文檔頂部描述的格式提供作為JSONL文件。

可以下載示例文件。

$ composer run-script index keyword sophp.jsonl

$ composer run-script index vector sophp.jsonl

要使用重讀索引，請單獨創建向量和關鍵字索引。

矢量索引大約需要一天，目前消耗了大量的RAM。

塊文件

遞歸塊可以獨立使用：

$ composer run-script chunk ropherta null 1024 tests/sornd1000.jsonl output.jsonl

輸出JSONL文檔具有密鑰：

• 標題（ title ）
• 文字（ text ）
• URL（ url ）
• 塊號（ chunk_num ）
• 偏移開始（ offset_start ）
• 偏移端（ offset_end ）
• 許可證（ license ）

其他標記器是可能的，請參見scripts文件夾中的代碼。使用字符串null （null）將大小設置為字符而不是令牌。

使用自定義ONNX模型的計算嵌入

$ composer run-script embed /path/to/model.onnx " actual text to compute embeddings " 

HYDE評級文件

使用完成服務（例如打開AI ChatGpt）來擴展答案：使用：

$ composer run-script hydrate /path/to/open-ai-key 1024 tests/sornd1000.jsonl output.jsonl

它從JSON對像中的title中填充了字段completion 。
