Overview

The range indicated by the word electronic dictionary is wide.Specifically, it is a portable type equipped with a dedicated LCD screen and keyboard.Electronic dictionary dedicated machine (IC electronic dictionary), Represented by dictionary search sites on the InternetOnline dictionary, Install and use on a computer equipped with a general-purpose OS such as a personal computer, smartphone, or tabletDictionary app, Read and use with an optical disk drive such as a personal computerCD-ROM dictionary(DVD-ROM dictionary),Dictionary function attached to the e-book readerand so on.further,Kana-Kanji conversion systemThe word meaning display function built into is also included in this.Generally speaking in Japan, "electronic dictionary" refers to the first portable electronic dictionary dedicated machine (electronic dictionary in a narrow sense).[2]..On the other hand, in Europe and the United States, "electronic dictionaries" generally refer to CD-ROM and DVD-ROM dictionaries.[3].

Features

A dictionary / encyclopedia that can record and play back data such as audio and video that could not be expressed on paper media.マ ル チ メ デ ィ アIt can be said that conversion is one of the features of electronic dictionaries.[4].

One of the advantages of electronic dictionaries when compared to paper dictionaries is

  • Since a large amount of information equivalent to hundreds of books can be collected in a small storage medium, it does not take up space for storage and storage and is easy to carry.[5]..Moreover, in the case of an online dictionary, since the dictionary data is held on the network, the storage capacity for storing the dictionary data is close to infinity.[6].
  • Even a dictionary with a large number of items can be searched faster than a thick paper dictionary.[6][7].
  • Various search methods such as prefix search, suffix search, partial match search, exact match search, and full text search may be prepared.[6][8]..In particular, dictionary files recorded according to a common standard can be searched in a batch (this is commonly called "skewer search").[9].
  • To other items such as related itemshyperlinkYou can easily move between items and even between dictionaries in the same way as (so-called "jump function").[6].

and so on.

On the contrary, the disadvantage is

  • No matter what kind of device you browse, you cannot escape from the restrictions on the size of the screen, so the amount of characters that can be viewed at one time is overwhelmingly smaller than that of a paper-based dictionary, and scrolling Then the previous information is hidden outside the screen[10](Comparing the book version, CD-ROM version, and electronic dictionary version of the 3th edition of Kojien, the display area of ​​the paper medium was about 9.3 times that of the CD-ROM version and about 36 times that of the electronic dictionary version. There are 2007 survey results[11]).
  • Due to the above restrictions, it is basically not suitable for comparing information from multiple dictionaries side by side.[8].
  • Depending on the usage environment such as a personal computer,Character codeFrom the difference ofGaijiEtc. may not be processed properly[12].
  • In paper dictionaries, there is no rule on where to put the legend and how to open it, which is customarily written at the beginning of the book.[13]Due to the variety of dictionary formats, the typical electronic dictionary is not constant.

and so on.

Standard / format

There are many electronic dictionary and encyclopedia software on the market, but the formats (formats and standards) such as the file format and directory structure of electronic dictionary data are common standards jointly formulated by multiple manufacturers. In addition to (EB, EPWING, etc.), there are quite a few software products created according to the original standards of each manufacturer.[14].

Of major electronic dictionary softwarefile formatIs

and so on.Except for ebooks, manyMicrosoft WindowsSuch ascomputerIt is a standard for.Moreover, even if a standard has been established, the specification is often kept private.this is,Copyright protectionIn addition to the point of view ofVendor lock-inIt is also thought that it was aimed at.

CD-ROM dictionary

As a historical background at the time of development, first in 1980SonyPhillipsStandards jointly developed byCD-DAA storage medium developed for (music CDs)compact disc (CD) [16]As an external storage medium for computersCD-ROMSpecification (Yellow Book) was proposed in 1983[17].. Each CD-ROM has a capacity of about 600.MBAt that time, it had a very large storage capacity, and because it could use the same production line as a music CD, it had the two advantages of being able to be mass-produced at low cost.Furthermore, it is expected to be a storage medium for dictionaries and encyclopedias that can fully utilize the large storage capacity of data collections and publications by taking advantage of the fatal defect of "non-rewritable". Was[16][17].

Then, in 1985, Japan's first CD-ROM dictionary "Latest Science and Technology Terminology Dictionary" was released.SanshushaReleased by[16][17][18]..The following year, in 1986, at that timeFujitsuDedicated word processorOASYSFor "KojienThe prototype of "1987rd edition CD-ROM version" was announced and released in XNUMX, the following year.[16][17]..this"Kojien"Third Edition CD-ROM Edition" is from Fujitsu, Sony,Iwanami Shoten-Dai Nippon PrintingCo-developed by[16]The dictionary format, called the WING Terms, was also provided free of charge to other companies.[17]..As a result, 1988Sanseido"Model Six Codes 62 CD-ROM version"Jiyuminsha"Basic knowledge of modern terminologyFollowing the release of the CD-ROM version, many dictionaries were produced and released in this format.[16][17].

After that, the WING rulesEPWINGEPWING is an electronic dictionary format that runs on Japanese personal computers, partly due to the dissemination activities of the EPWING Consortium, an organization established in 1991 by gathering publishers, printing companies, software makers, and hardware makers.De facto standardFinally, in 1997, "Japanese Electronic Publishing Search Data Structure" (JIS X 4081) Was standardized by JIS[16][17].. The EPWING format electronic dictionary was discontinued on October 2012, 10, and has been the successor standard since then.ONESWINGIs migrating to[19].

Another electronic dictionary format derived from the WING convention, Sony's originalEbook (EB)There is[17]..In the same year that the EPWING Consortium was established under the initiative of Fujitsu, Sony led the organization of a similar organization, the "Electronic Book Committee," and promoted the spread of electronic books.[17]..Unlike ordinary CD-ROMs, ebooks use 8 cm CD-ROMs.caddyPut it in a case called, and take the form of using it with the dedicated hardware "ebook player"[17]..The first ebook player was released by Sony in 1990.(English edition DD-1 ", laterSanyo Electric,Matsushita Electric IndustrialPlayer was released from[17]..Initially, it was prohibited to use the CD-ROM with the caddy removed directly on a personal computer, etc., but the ban was lifted in 1994, and with the advent of freeware dictionary search software (electronic book viewer), Popular as an electronic dictionary for personal computers[17]..Ebook player sales ended in 2000[20].

As mentioned above, the standard formats of Japanese CD-ROM dictionaries were EPWING and electronic books, but CD-ROM dictionaries of their own standards, which are neither of them, were also developed and sold by each company.[17]..The most representative of these is平凡 社of"World Encyclopedia(1992),MicrosoftCompanyMicrosoft Bookshelf(1997),Shogakukanof"Super Nipponica(1998)[17].

In addition, in electronic encyclopedias including audio and images, the storage capacity becomes larger as the amount of data increases.DVD-ROM,USB memoryHas also appeared as a recording and distribution medium[2].. As of 2010, it is the mainstream to install and use the data in the storage device built in the device instead of reading the data directly from these external storage media.[12], The actual usage pattern will be described later.Dictionary appThe distinction from is becoming ambiguous.

Electronic dictionary dedicated machine (IC electronic dictionary)

Before and after the release of CD-ROM dictionaries, the storage medium for electronic dictionariesCD-ROMからIC memoryMoving to[21], An IC electronic dictionary that integrates a storage medium and a search / display device will appear.

First Generation (1979-1985): Calculator-type electronic vocabulary

In the Japanese domestic marketsharpReleased in November 1979Pocket translator (IQ-3000) is the first[22][23][24][25]It was 39,800 yen, which was quite expensive at that time.[Source required]. this isMasayoshi SonIt is said that it is based on the automatic translator that he invented when he was a student.[26].. IQ-3000 recorded about 2800 English-Japanese words and about 5000 Japanese-English words.[25]But technicallycalculatorIt is an application of technology[27], Only alphabets and katakana could be displayed on the 16-digit x 1-line monochrome LCD screen.[17][24]..The content is more like a vocabulary than a dictionary,Vocabulary BookIt was a product that should be called a calculator with a function[17][24]..At that time, the manufacturing cost of IC memory and LCD display was high, so inexpensive small-capacity on-board memory and a small LCD screen were adopted.[27], The number of words in the dictionary has peaked, and the display capacity of the LCD screen has also been limited.[24].

In the 1980s, in April 1980CanonReleased the electronic English word "LA-1000" (includes 1320 English-Japanese words and 2180 Japanese translations), and in October 1981.Casio calculatorAlso released the electronic English-Japanese dictionary "TR-2000" (containing about 2000 English words and idioms)[28]Entered the market[17]..However, in order to completely record one dictionary, we had to wait for the capacity and price of IC memory to increase.[21].

Third Generation (1990-1995): Introducing Full Content Dictionaries

As a portable electronic dictionary derived from the development of the CD-ROM dictionary, Sony released the electronic book player "DATA Discman DD-1" in July 1990 (see details).CD-ROM dictionaryreference).And the first full-scale IC electronic dictionary in Japan isResearch societyThe IC dictionary "TR-1992" released by Seiko Denshi Kogyo in January 1, which contains all the character information of the two volumes of Kenkyusha's "New English-Japanese / Japanese-English Chinese Dictionary", was called a full-content dictionary.[21][24][29]..Since then, the mainstream of electronic dictionaries has shifted to IC electronic dictionaries.[21], The IC dictionary will also be polarized into a full-content type full-scale electronic dictionary and an inexpensive simple electronic dictionary called a standard type, mainly due to differences in usability and shape.[24].

Fourth Generation (1996-1999): Full Content Market Expansion

The price of IC memory and liquid crystal display has been reduced, and a full-content electronic dictionary containing a large liquid crystal screen and multiple dictionaries has appeared, and the IC electronic dictionary market in Japan has begun to grow significantly.[24]..Also, Sony's DD-IC series[30]A full-content dictionary about the size of a business card case has also appeared.[24]..Demand for electronic dictionaries has increased, and the number of customers who purchase them has expanded, but the mainstream of the electronic dictionary market at that time was the inexpensive standard type.[24].

Fifth generation (2000-2002): Expansion of recording dictionaries and diversification of product lineup

As the decline in semiconductor prices has accelerated and the number of digitized dictionary data provided by publishers has increased, it has become possible to record a large amount of dictionary data in one unit, and many dictionaries can be stored.

2003th Generation (2006-XNUMX): Multi-functional dictionary

In order to differentiate from other companies' products, each company will develop products with unique functions.[24]..Specifically, it has a voice pronunciation function, an additional function for content using an extended memory card, a color LCD (the industry's first Sharp "PW-C2002" released in 5000), and a handwriting input system.[24]..The contents to be recorded are not limited to dictionaries and encyclopedias such as specialized dictionaries, large dictionaries, Japanese dictionaries, and encyclopedias, but also study books, hobbies, and practical books are actively recorded.[24]..In addition, while product development has begun to look not only in Japan but also in overseas markets, the standard market has declined.[24].

2006th Generation (XNUMX-): Electronic dictionaries that go beyond mere dictionaries

It is thought that the period from 2006 to 2010 was a transitional period from monochrome LCDs to color LCDs.[24]..In addition, high-definition liquid crystal display, introduction of handwriting input pad and touch panel liquid crystal, installation of multilingual pronunciation function and text reading (TTS) function, recording of video content, installation of English learning support function,One SegProducts with various features such as built-in functions were developed one after another[24].. However,SmartphoneWith the appearance ofDictionary appDue to the spread of the Internet and the rise of free dictionary sites on the Internet, the number of units sold has been declining since 2008.[21]..On the other hand, even in such a predicament, the demand for learning electronic dictionaries for high school and college students seems to be alive and well.[21][31].
