Japanese university students, begin using E-mails frequently when they start looking for a job. They also use E-mails in communication with professors. In these cases, the E-mail is required to have a specific structure. It should consist of six parts, such as, \"Addressee's Name\", \"Self-Introduction\", \"Preamble\", \"Main Body\", \"Closing Remarks\", and \"Signature\". \"Addressee's Name\" should appear at the top of the E-mail, and include the name, affiliation, or an official position of the addressee. The E-mail has the address information itself, but \"Addressee's Name\" is needed for the addressee to know if the E-mail is addressed to them in case of the E-mail being sent to multiple people. This element is crucial when sending the message to someone who does not know the sender, but is required even if both sides know each other. \"Self-Introduction\" is necessary to appear after the \"Addressee's Name\", and include sender's name, affiliation, or an official position. Like \"Addressee's Name\", although E-mail header contains this information, \"Self-Introduction\" should appear in the E-mail text anyway. It can be shortened when both sides know each other, but in official situation lack of this part will result in miscommunication, or even disregarding the whole E-mail by the receiver. \"Preamble\" is an element of simple greetings. Before starting with the main text, it is necessary to include this element in the E-mail text. One should avoid simple daytime-based or seasonal greetings (e.g., \u3053\u3093\u3070\u3093\u306f Konbanwa \"Good evening,\"), and instead use formal greeting phrases, such as \u3044\u3064\u3082\u304a\u4e16\u8a71\u306b \u306a\u308a\u307e\u3059 Itsumo osewa ni narimasu \"I am in your debt for your constant help\". \"Main Body\" is the main part of E-mail text. This element describes what the sender wants to discuss.There are no specific honorific phrases to use here, but introduction to the main topic should always be explicit, e.g., X \u306e\u4ef6\u306b\u3064\u3044\u3066 X-no ken ni tsuite \"Regarding the case of X...\", etc. \"Closing Remarks\" should contain simple greetings after the explanation of the topic in \"Main Body\". This element mainly uses text that requests the mail receiver to review the topic of the email or requests a response from the mail receiver. \"Signature\" is a detailed description of the sender's information, containing affiliation, postal code, address, E-mail address, phone number and URL for website, etc.", "cite_spans": [], "ref_spans": [], "eq_spans": [], "section": "Rules of Japanese E-mail Etiquette", "sec_num": "2.1" }, { "text": "Despite the importance of E-mail literacy in Japan, there has been a growing problem of deficiency in its education.

They conducted a survey on university students asked about their learning experience of E-mail literacy. As a result,13 out of 20 (65%) Japanese students answered they never learned E-mail literacy.

In the assumption the system is meant to be used as an educational tool to help Japanese students increase their E-mail literacy. The system can be separated into three main sections, namely, \"Input Section\", \"E-mail Contents Analysis Section\", \"Output Section\". \"Input Section\" is responsible for obtaining the text of the E-mail, and performing initial preprocessing such as text cleaning (removing unnecessary spaces, and symbols) or sentence segmentation for further analysis. \"Analysis Section\" is responsible for a structure analysis based on specific E-mail patterns. These patterns were created from the annotated data of Japanese E-mail examples collected in advance. \"Output Section\" is responsible for providing specific advises depending on the result of analysis from the previous section.
