3gpp Embedding Model V0

🚀 BGE_base_3gpp-qa-v2_Matryoshka

这是一个基于 sentence-transformers 的模型，它在 json 数据集上对 BAAI/bge-base-en-v1.5 进行了微调。该模型可以将句子和段落映射到一个 768 维的密集向量空间，可用于语义文本相似度、语义搜索、释义挖掘、文本分类、聚类等任务。

🚀 快速开始

直接使用（Sentence Transformers）

首先安装 Sentence Transformers 库：

pip install -U sentence-transformers

然后，你可以加载这个模型并进行推理。

from sentence_transformers import SentenceTransformer

# 从 🤗 Hub 下载
model = SentenceTransformer("iris49/3gpp-embedding-model-v0")
# 进行推理
sentences = [
    'What types of data structures are supported by the GET request body on the resource described in table 5.2.11.3.4-2, and how do they influence the request?',
    "The data structures supported by the GET request body on the resource are detailed in table 5.2.11.3.4-2. These structures define the format and content of the data that can be sent in the request body. They might include fields such as 'filterCriteria', 'sortOrder', or 'pagination', which influence how the server processes the request and returns the appropriate data.",
    "The specific triggers on the Ro interface that can lead to the termination of the IMS service include: 1) Reception of an unsuccessful Operation Result different from DIAMETER_CREDIT_CONTROL_NOT_APPLICABLE in the Debit/Reserve Units Response message. 2) Reception of an unsuccessful Result Code different from DIAMETER_CREDIT_CONTROL_NOT_APPLICABLE within the multiple units operation in the Debit/Reserve Units Response message when only one instance of the multiple units operation field is used. 3) Execution of the termination action procedure as defined in TS 32.299 when only one instance of the Multiple Unit Operation field is used. 4) Execution of the failure handling procedures when the Failure Action is set to 'Terminate' or 'Retry & Terminate'. 5) Reception in the IMS-GWF of an Abort-Session-Request message from OCS.",
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# 获取嵌入向量的相似度得分
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]

训练数据集

json

• 数据集：json
• 大小：56,041 个训练样本
• 列：anchor 和 positive
• 基于前 1000 个样本的近似统计信息： | | anchor | positive | | ---- | ---- | ---- | | 类型 | 字符串 | 字符串 | | 详情 |
  • 最小值：15 个标记
  • 平均值：30.56 个标记
  • 最大值：66 个标记
  |
  • 最小值：42 个标记
  • 平均值：109.65 个标记
  • 最大值：298 个标记
  |
• 样本： | anchor | positive | | ---- | ---- | | What does the 'dataStatProps' attribute represent in the 'AnalyticsMetadataInfo' type, and what is its data type? | The 'dataStatProps' attribute in the 'AnalyticsMetadataInfo' type represents a list of dataset statistical properties of the data used to generate the analytics. It is defined as an optional attribute with a data type of 'array(DatasetStatisticalProperty)' and a cardinality of 1..N, meaning it can contain one or more elements. | | Why is it important to have standardized methods for resource management in the Nudm_SubscriberDataManagement Service API? | Standardized methods for resource management in the Nudm_SubscriberDataManagement Service API are important because they ensure uniformity, predictability, and compatibility across different implementations and systems. This standardization facilitates seamless integration, reduces errors, and enhances the efficiency of managing subscriber data, which is critical for maintaining reliable communication services. | | What is the purpose of the Nsmf_PDUSession_SMContextStatusNotify service operation in the context of I-SMF context transfer? | The Nsmf_PDUSession_SMContextStatusNotify service operation is used by the SMF (Session Management Function) to notify its consumers about the status of an SM (Session Management) context related to a PDU (Packet Data Unit) Session. In the context of I-SMF (Intermediate SMF) context transfer, this service operation is used to indicate the transfer of the SM context to a new I-SMF or SMF set. It also allows the SMF to update the SMF-derived CN (Core Network) assisted RAN (Radio Access Network) parameters tuning in the AMF (Access and Mobility Management Function). Additionally, it can report DDN (Downlink Data Notification) failures and provide target DNAI (Data Network Access Identifier) information for the current or next PDU session. |
