关系抽取：SemEval2010 Task8数据集

任务描述

SemEval2010 Task8详细信息请参考官方文档。

任务：

对于给定了的句子和两个做了标注的名词，从给定的关系清单中选出最合适的关系。

关系清单（9+1）如下所示：

关系	定义	例子
Cause-Effect （因果关系）	Cause-Effect(X, Y)  is true for a sentence S that mentions entities X and Y if and only if (1) S, X and Y are in accordance with the general annotation guidelines (http://docs.google.com/Doc?docid=dfhkmm46_0f63mfvf7) (2) the situation described in S entails that X is the cause of Y, or that X causes/makes/produces/emits/... Y.	"A person infected with a particular flu virus strain develops an antibody against that virus." Cause-Effect(e2, e1) Comment: flu is a state, virus is the causal agent, thus (a) is satisfied; the virus is actively involved in causing flu and thus (c) is satisfied.
Instrument-Agency	Instrument-Agency(X, Y) is true of a sentence S that mentions entities X and Y if and only if: (1) S, X and Y are in accordance with the general annotation guidelines (http://docs.google.com/Doc?docid=dfhkmm46_0f63mfvf7) (2) the situation described in S entails the fact that X is the instrument (tool) of Y or, equivalently, that Y uses X.	"A person infected with a particular flu virus strain develops an antibody against that virus." Cause-Effect(e2, e1) Comment: flu is a state, virus is the causal agent, thus (a) is satisfied; the virus is actively involved in causing flu and thus (c) is satisfied.
Product-Producer （生产与被生产之间的关系）	Product-Producer (X, Y) is true for a sentence S that mentions entities X and Y if and only if: (1) S, X and Y are in accordance with the general annotation guidelines (http://docs.google.com/Doc?docid=dfhkmm46_0f63mfvf7) (2) the situation described in S entails the fact that X is a product of Y, or Y produces X.	"The honey bee is the third insect genome published by scientists, after a lab workhorse, the fruit fly, and a health menace, the mosquito." Product-Producer(e1, e2) Comment: This is a typical example of Product-Producer. Honey is a tangible concrete object (c), and the bee is actively involved in producing it (a).
Content-Container	Content-Container(X, Y) is true for a sentence S that mentions entities X and Y if and only if (1) S, X and Y are in accordance with the general annotation guidelines (http://docs.google.com/Doc?docid=dfhkmm46_0f63mfvf7) (2) the situation described in S entails that X is or was (usually temporarily) stored or carried inside Y.	"The apples are in the basket." Content-Container(e1, e2) Comment: This is a prototypical example of Content-Container.
Entity-Origin	Entity-Origin(X, Y) is true for a sentence S that mentions the entities X and Y if and only if (1) S, X and Y are in accordance with the general annotation guidelines (http://docs.google.com/Doc?docid=dfhkmm46_0f63mfvf7) (2) the situation described in S entails that Y is the origin of an entity X (rather than its location), and X is coming or derived from that origin.	"Under state law, minors are not permitted to have grain alcohol, even if a parent provides it to their children." Entity-Origin(e2, e1) Comment: This is a prototypical example of a material Entity-Origin relation. Restriction (b.4) applies.
Entity-Destination	Entity-Destination(X, Y) is true for a sentence S that mentions the entities X and Y if and only if: (1) S, X and Y are in accordance with the general annotation guidelines (http://docs.google.com/Doc?docid=dfhkmm46_0f63mfvf7) (2) the situation described in S entails the fact that Y is the destination of X in the sense of X moving (in a physical or abstract sense) toward Y.	"Theboy ran into the school cafeteria." Entity-Destination(e1,e2) Comment: school cafeteria is a spatial/geographical destination.
Component - Whole	Component-Whole (X,Y) is true for a sentence S that mentions entities X and Y if and only if: (1) S, X and Y are in accordance with the general annotation guidelines (http://docs.google.com/Doc?docid=dfhkmm46_0f63mfvf7) (2) the situation described in S entails that X is a component of Y; (3) X has a functional relation with Y. In other words, X has an operating or usable purpose within Y.	We don't need Einstein's quantum mechanics to understand why each hand has 5 fingers, and not 4 or 6. Component-Whole(e2, e1) Comment: Fingers are functional, integral parts of the hand.
Member-Collection	Member-Collection(X, Y) is true for a sentence S that mentions entities X and Y if and only if: (1) S, X and Y are in accordance with the general annotation guidelines (http://docs.google.com/Doc?docid=dfhkmm46_0f63mfvf7) (2) the situation described in S entails the fact that X is a member of Y.	"Italian playing cards most commonly consist of a deck of 40 cards." Member-Collection(e2, e1) Comment: A deck is a collection of cards, cards are different and separable from the deck, not functional to the deck.
Message-Topic	Message-Topic(X, Y) is true for a sentence S that mentions the entities X and Y if and only if:   (1) S, X and Y are in accordance with the general annotation guidelines (http://docs.google.com/Doc?docid=dfhkmm46_0f63mfvf7)   (2) the situation described in S entails the fact that X is a communicative message containing information about Y.	"The recommendations contained the following key points about the new politics of the government." Message-Topic(e1, e2) Comment: politics is the topic of the key points.
Other	当句子中实体之前不满足前九种关系时，将标签设置为Other

各类数据的占比如下图所示：

                      

数据集

1. Trial Dataset：试验数据集于2009年8月30日发布，它包含前五个关系的数据。但是，其中也包含了一些其他四种关系的引用，  这些数据在试验数据集上可以被视为Other关系，而不必多加处理。
2. Training Dataset:训练集包含8000个样例，涵盖上文提到的9+1中关系。
3. Development Dataset：没有提供官方开发集，但是参与者可以使用该部分训练数据集来调整期参数，如使用交叉验证。
4. Test Dataset：测试集包含2717个样例，涵盖上文提到的9+1中关系，于2010年3月18日发布。
5. WordNet senses提示：和SemEval-2007 Task 4不同，此处不提供人工标注的WordNet senses，会使得任务更加真实。

SemEval-2010 Task 8 VS SemEval-2007 Task 4

• l相比于2007中对于每一种关系提供一个单独的数据集和一个对应的二分类任务，2010仅仅提供一个单独的多类别数据集。
• l多分类任务
• l候选的实体仍然会提供，但是评测系统需要去决策实体在关系中的槽位。
• lWordNet senses 和 query strings将不再提供。
• l数据集中数据量大了很多（超过10000条标记的句子）。
• l关系的集合也变大了

难点

关系清单种中两组相近的关系：

l组1：

• lComponent-Whole
• lMember-Collection
• l都是Part-Whole的特殊情况

l组2：

• lContent-Container
• lEntity-Origin
• lEntity-Destination
• l可以通过考虑所表达的状态是静态的还是动态的进行区分
