A knowledge base can be integrated as a whole into an application to be used as context. Documents can be uploaded by developers or operations staff, or synced from other data sources (typically corresponding to a file unit in the data source). - -**Steps to upload a document:** - -1. Upload your file, usually a long text file or a spreadsheet -2. Segment, clean, and preview -3. Dify submits it to the LLM provider for embedding as vector data and storage -4. Set metadata for the document -5. Ready to use in the application! - -#### How to write a good knowledge description - -When multiple knowledge bases are referenced in an application, AI uses the description of the knowledge and the user's question to determine which knowledge base to use to answer the user's question. Therefore, a well-written knowledge description can improve the accuracy of AI in selecting knowledge. - -The key to writing a good knowledge description is to clearly describe the content and characteristics of the knowledge. **It is recommended that the knowledge description begin with this: `Useful only when the question you want to answer is about the following: specific description`**. Here is an example of a real estate knowledge description: - -> Useful only when the question you want to answer is about the following: global real estate market data from 2010 to 2020. This data includes information such as the average housing price, property sales volume, and housing types for each city. In addition, this knowledge base also includes some economic indicators such as GDP and unemployment rate, as well as some social indicators such as population and education level. These indicators can help analyze the trends and influencing factors of the real estate market. With this data, we can understand the development trends of the global real estate market, analyze the changes in housing prices in various cities, and understand the impact of economic and social factors on the real estate market. - -### Create a knowledge - -1.

If you have already prepared your files, you can start by uploading the files. -3. If you haven't prepared your documents yet, you can create an empty knowledge base first. - -### Uploading Documents By upload file - -1. Select the file you want to upload.We support batch uploads -2. Preview the full text -3. Perform segmentation and cleaning -4. Wait for Dify to process the data for you; this step usually consumes tokens in the LLM provider - -### Text Preprocessing and Cleaning - -Text Preprocessing and cleaning refers to Dify automatically segmenting and vectorizing your data documents so that user's questions (input) can match relevant paragraphs (Q to P), and generate results. - -When uploading a knowledge base, you need to select a **indexing mode** to specify how data is matched. This affects the accuracy of AI replies. - -In **High Quality mode**, OpenAI's embedding API is used for higher accuracy in user queries. - -In **Economic mode**, offline vector engines, keyword indexing etc. are used to reduce costs at the expense of lower accuracy. - -In **Segmenting in Question & Answer format**, instead of normal "Q to P" (question matches paragraphs), it uses "Q to Q" (question matches question) matching. After segmentation, Q\&A pairs are generated for each passage. When users ask questions, the system finds the most similar question and returns the corresponding passage as the answer. This is more precise because it directly matches the user's question and retrieves the information they need. - -> Questions have complete syntax while keywords lack semantics and context. So Q to Q improves clarity and handles similar high-frequency questions better. - -

A representative example of a RAG application is as follows: - -In the diagram below, when a user asks, "Who is the President of the United States?", the system doesn't directly relay the question to the large model for an answer. Instead, it first conducts a vector search in a knowledge base (like Wikipedia, as shown in the diagram) for the user's query. It finds relevant content through semantic similarity matching (for instance, "Biden is the current 46th President of the United States…"), and then provides the user's question along with the found knowledge to the large model. This enables the model to have sufficient and complete knowledge to answer the question, thereby yielding a more reliable response. - -

Basic Architecture of RAG

- -## Why is this necessary? - -We can liken a large model to a super-expert, knowledgeable in various human domains. However, this expert has its limitations; for example, it doesn't know your personal situation, as such information is private and not publicly available on the internet, and therefore, it hasn't had the opportunity to learn it beforehand. - -When you want to hire this super-expert as your family financial advisor, you need to allow them to review your investment records, household expenses, and other relevant data before they can respond to your inquiries.

The technical principle involves initially dividing documents from external knowledge bases into semantically complete paragraphs or sentences, and then converting them through a process known as embedding into a series of numerical expressions (multidimensional vectors) that computers can understand. The user's query undergoes a similar conversion. - -Computers can detect subtle semantic correlations between user queries and sentences. For example, the semantic relevance between "a cat chases a mouse" and "a kitten hunting a mouse" is higher than between "a cat chases a mouse" and "I like to eat ham." After identifying the text with the highest relevance, the RAG system provides it as context alongside the user's query to the large model, aiding in answering the question. - -Besides complex semantic text searches, Vector Search has other advantages: - -* Understanding of similar semantics (e.g., mouse/mousetrap/cheese, Google/Bing/search engine) -* Multilingual comprehension (e.g., matching Chinese input with English content) -* Multimodal understanding (supports matching text, images, audio, and video) -* Fault tolerance (handles spelling mistakes, vague descriptions) - -However, Vector Search might underperform in certain scenarios, like: - -* Searching names of people or objects (e.g., Elon Musk, iPhone 15) -* Searching acronyms or short phrases (e.g., RAG, RLHF) -* Searching IDs (e.g., `gpt-3.5-turbo`, `titan-xlarge-v1.01`) - -These limitations are precisely where traditional keyword search excels, being adept at: - -* Precise matching (e.g., product names, personal names, product numbers) -* Matching a small number of characters (vector search performs poorly with few characters, but users often input just a few keywords) -* Matching low-frequency vocabulary (which often carries more significant meanings, like in “Do you want to go for a coffee with me?”, words like “drink” and “coffee” carry more weight than “you”, “want”, “me”) - -In most text search scenarios, it's crucial to ensure that the most relevant results appear in the candidates. Vector and keyword searches each have their strengths in the search domain. Hybrid Search combines the advantages of both techniques while compensating for their respective shortcomings. - -In Hybrid Search, vector and keyword indices are pre-established in the database. Upon user query input, the system searches for the most relevant text in documents using both search methods. - -

For instance, we could combine knowledge graph technology, used for retrieving entity relationships, with Vector Search. - -Different search systems each excel at uncovering various subtle connections within texts (paragraphs, sentences, words), including precise relationships, semantic relationships, thematic relationships, structural relationships, entity relationships, temporal relationships, and event relationships. It's safe to say that no single search mode is suitable for all scenarios. **Hybrid Search, by integrating multiple search systems, achieves a complementarity among various search technologies.** - -## Vector Search - -Definition: Vector Search involves generating query embeddings and then searching for text chunks that most closely match these embeddings in terms of vector representation. - -

This mode is more suitable for applications with fewer knowledge bases. - -Tip: OpenAI Function Call already supports multiple tool calls, and Dify plans to upgrade this mode to "N-to-M retrieval" in future versions. - -### Multi-path Retrieval - -Based on user intent, this mode matches all knowledge bases simultaneously, queries relevant text chunks from multiple knowledge bases, and after a re-ranking step, selects the best results matching the user's question from the multi-path query results. Configuring the Rerank model API is required. In Multi-path retrieval mode, the search engine retrieves text content related to the user's query from all knowledge bases associated with the application, merges the results from multi-path recall, and re-ranks the retrieved documents semantically using the Rerank model. - -In Multi-path retrieval mode, configuring the Rerank model is necessary. How to configure the Rerank model: 🔗 - -Here is the technical flowchart for Multi-path retrieval: - -

Multi-path retrieval

- -As Multi-path retrieval does not rely on the model's inferencing capability or knowledge descriptions, this mode can achieve higher quality recall results in multi-knowledge searches. Additionally, incorporating the Rerank step can effectively improve document recall. Therefore, when creating a knowledge base Q\&A application associated with multiple knowledge bases, we recommend configuring the retrieval mode as Multi-path retrieval. diff --git a/en/features/workflow/nodes/README.md b/en/features/workflow/nodes/README.md deleted file mode 100644 index 7ab6344..0000000 --- a/en/features/workflow/nodes/README.md +++ /dev/null @@ -1,2 +0,0 @@ -# Nodes - diff --git a/en/features/workflow/nodes/answer.md b/en/features/workflow/nodes/answer.md deleted file mode 100644 index ff31984..0000000 --- a/en/features/workflow/nodes/answer.md +++ /dev/null @@ -1,23 +0,0 @@ ---- -description: Answer ---- - -# Answer - -Defining Reply Content in a Chatflow Process.

Select the document you need to upload from your local files; +2. Segment and clean the document, and preview the effect; +3. Choose and configure Index Mode and Retreival Settings; +4. Wait for the chunks to be embedded; +5. Upload completed, now you can use it in your applications 🎉 + +**Limitations for uploading documents:** + +* The upload size limit for a single document is 15MB; +* The maximum number of files for a single batch upload is 20; +* Different [subscription plans](https://dify.ai/pricing) for the SaaS version limit **batch upload numbers, total document uploads, and vector storage**; + +### 3 Segmenting and Cleaning + +**Segmenting**: Large language models have a limited context window, usually requiring the entire text to be segmented and then recalling the most relevant segments to the user’s question, known as the segment TopK recall mode. Additionally, appropriate segment sizes help match the most relevant text content and reduce information noise when semantically matching user questions with text segments. + +**Cleaning**: To ensure the quality of text recall, it is usually necessary to clean the data before passing it into the model. For example, unwanted characters or blank lines in the output may affect the quality of the response. To help users solve this problem, Dify provides various cleaning methods to help clean the output before sending it to downstream applications. + +Segmentation and cleaning support two configuration strategies: + +* Automatic mode (to be phased out) +* Custom mode + +
+ +In custom mode, users can configure chunk settings and cleaning settings according to different document formats and scenario requirements. + +**Segmentation rules:** + +* Segmentation identifier, set an identifier such as "\n", and the system will segment the text when the identifier appears in the text; +* Maximum segment length, segment based on the maximum character limit of the text, forcibly segmenting when exceeding this length; +* Segment overlap length, set the number of overlapping characters between segments, it is recommended to set it to 10-25% of the segment length, which helps retain semantic relevance between segments and improves recall results during multi-segment recall. + +**Preprocessing rules:** + +* Replace continuous spaces, newlines, and tabs; +* Delete all URLs and email addresses; + +*** + +### 4 Optional ETL Configuration + +In production-level applications of RAG, to achieve better data recall, multi-source data needs to be preprocessed and cleaned, i.e., ETL (extract, transform, load).

The indexing strategy is often related to the retrieval method, and you need to choose the appropriate indexing method according to the scenario. + +**High-Quality Mode**: Calls OpenAI's embedding interface for processing, providing higher accuracy during user queries. + +**Economy Mode**: Uses keyword indexing, reducing accuracy but not requiring token costs. + +**Q\&A Mode (community version only)**: The Q\&A segment mode function differs from the ordinary "Q to P" (question to paragraph) matching mode mentioned above. It uses the "Q to Q" (question to question) matching mode. After the document is segmented, each segment generates a Q\&A matching pair through summarization. When a user asks a question, the system finds the most similar question and returns the corresponding segment as the answer. This method is more precise because it directly matches the user’s question, accurately obtaining the information the user truly needs. + +When uploading documents to the knowledge base, the system segments the text so that the user's questions (input) can match the relevant text segments (Q to P), and finally output the result. + +> Question text is natural language with complete grammatical structure, not just some keywords in a document retrieval task. Therefore, the Q to Q (question matching question) mode makes semantics and matching clearer and meets the needs of high-frequency and high-similarity question scenarios. + +

After a re-ranking step, the best result matching the user question is selected from the multi-path query results. Requires configuration of the Rerank model API. + +
+ +**How to Choose a Recall Mode** + +N-Choose-1 Recall is driven by Function Call/ReAct, where each associated knowledge base acts as a tool function. The LLM autonomously selects the most relevant knowledge base to query based on the semantic match between the user question and the knowledge base description. + +The effectiveness of the N-Choose-1 mode is influenced by three main factors: + +* **The reasoning capability of the system model:** Some models have unstable adherence to Function Call/ReAct instructions. +* **Clarity of the knowledge base description:** The description content affects the LLM's reasoning about the user question and the related knowledge base. +* **Number of knowledge bases:** Too many knowledge bases can affect the LLM's reasoning accuracy and may exceed the context window length of the reasoning model. + +**Recommended Configuration for N-Choose-1 Mode:** Choose a system reasoning model with better performance, associate as few knowledge bases as possible, and provide precise knowledge base descriptions. + +When users upload a knowledge base, the system reasoning model automatically generates a summary description for the knowledge base.

You can configure them as needed in Dify. For specific differences between the two integration methods, please refer to [Notion Official Documentation](https://developers.notion.com/docs/authorization). + +### 1. **Using Internal Integration** + +First, create an integration in the integration settings page [Create Integration](https://www.notion.so/my-integrations). By default, all integrations start as internal integrations; internal integrations will be associated with the workspace you choose, so you need to be the workspace owner to create an integration. + +Specific steps: + +Click the **New integration** button. The type is **Internal** by default (cannot be modified). Select the associated space, enter the integration name, upload a logo, and click **Submit** to create the integration successfully. + +
+ +After creating the integration, you can update its settings as needed under the Capabilities tab and click the **Show** button under Secrets to copy the secrets. + +
+ +After copying, go back to the Dify source code, and configure the relevant environment variables in the **.env** file. The environment variables are as follows: + +**NOTION\_INTEGRATION\_TYPE**=internal or **NOTION\_INTEGRATION\_TYPE**=public + +**NOTION\_INTERNAL\_SECRET**=your-internal-secret + +### 2. **Using Public Integration** + +**You need to upgrade the internal integration to a public integration.** Navigate to the Distribution page of the integration, and toggle the switch to make the integration public.

+ +After successfully making the integration public on the integration settings page, you will be able to access the integration key in the Keys tab: + +
+ +Go back to the Dify source code, and configure the relevant environment variables in the **.env** file. The environment variables are as follows: + +**NOTION\_INTEGRATION\_TYPE**=public + +**NOTION\_CLIENT\_SECRET**=your-client-secret + +**NOTION\_CLIENT\_ID**=your-client-id + +After configuration, you can operate the Notion data import and synchronization functions in the dataset. \ No newline at end of file diff --git a/en/tutorials/model-configuration/README.md b/en/guides/model-configuration/README.md similarity index 100% rename from en/tutorials/model-configuration/README.md rename to en/guides/model-configuration/README.md diff --git a/en/guides/model-configuration/customizable-model.md b/en/guides/model-configuration/customizable-model.md new file mode 100644 index 0000000..3d5df38 --- /dev/null +++ b/en/guides/model-configuration/customizable-model.md @@ -0,0 +1,300 @@ +# 自定义模型接入 + +### 介绍 + +供应商集成完成后，接下来为供应商下模型的接入，为了帮助理解整个接入过程，我们以`Xinference`为例，逐步完成一个完整的供应商接入。 + +需要注意的是，对于自定义模型，每一个模型的接入都需要填写一个完整的供应商凭据。 + +而不同于预定义模型，自定义供应商接入时永远会拥有如下两个参数，不需要在供应商 yaml 中定义。 + +

`Generator`，因此同步和流式返回需要分别实现，就像下面这样（注意下面例子使用了简化参数，实际实现时需要按照上面的参数列表进行实现）： + + ```python + def _invoke(self, stream: bool, **kwargs) \ + -> Union[LLMResult, Generator]: + if stream: + return
