Children’s bet365 bonus bets is used to study children’s behavior、An important basis for exploring the mechanism of language acquisition。1787，German psychologist、The "Diary of Infant Behavior" published by the philosopher Dietrich Tiedemann is the earliest work to record children's language。1960s，With the development of bet365 bonus bets linguistics and computer technology，The rise of children’s bet365 bonus bets construction。The Okayama bet365 bonus bets constructed in 1969 is among the first batch of preschool children’s corpora constructed in the world。According to incomplete statistics，The bet365 bonus bets of preschool children in the world has reached more than 350。The construction history and development trend of the world preschool children bet365 bonus bets，Can be grasped from two levels: bet365 bonus bets technology and bet365 bonus bets content。

　　Preschool children bet365 bonus betsConstruction Technology: “Three Modernizations”

Overview of the development process of bet365 bonus bets construction technology for preschool children around the world，Especially the development and changes in the past forty years，Its characteristics can be summarized as "three modernizations"。

First，Digitization of bet365 bonus bets collection technology。Transcript of children’s bet365 bonus bets collection technology experience、Recording、Three technical stages of video recording。In the early days, transcripts were mainly used、Collecting children’s bet365 bonus bets using diary method；Then began to use recording technology，The first to use recording technology to collect children's bet365 bonus bets was Japan's Okayama Children's bet365 bonus bets；1970s，The Menn Children's bet365 bonus bets in the United States uses video technology to collect children's bet365 bonus bets for the first time。80s to 90s，Text、Recording、Video technology is adopted。Enter the 21st century，Traditional written records and tape recordings、Video recording is gradually declining，Digital audio and video recording technology has emerged and been widely used。The popularity of portable recording equipment allows people to collect children’s bet365 bonus bets anytime and anywhere。Statistics，Except children's bet365 bonus bets of unknown construction year，20th century to 21st century，The proportion of children’s bet365 bonus bets construction using written records dropped from about 10% to 1%，The use of recording dropped from 42% to 30%，The use of video recording increased from about 28% to 32%。Overall，Children’s bet365 bonus bets collection technology has gradually become digital and ubiquitous，And reflected from print media、The development trend of audio media towards multimedia。However, compared with other more mature language resource construction，Construction of children’s bet365 bonus bets for artificial intelligence、There is still a gap in the application of advanced technologies such as cloud computing。

Second，Diversified bet365 bonus bets collection methods。Children’s bet365 bonus bets collection methods include natural observation method、Interview method、Experimental method、Network collection method, etc.。Before 1970s，Natural observation method is the main or even the only method for bet365 bonus bets collection。Afterwards，Except natural observation method，Start using the interview method、Collecting children’s bet365 bonus bets using experimental methods。21st century，With the development of Internet technology，CHCC Children’s bet365 bonus bets and others began to gather children’s corpora on the Internet。20th century to 21st century，The application of natural observation method dropped from 81% to 68%，Experimental method increased from 16% to 37%，The application rate of interview method has also declined significantly。The collection method directly affects the naturalness and initiative of the respondent’s language production，Contemporary children's corpora should use a variety of collection methods and adapt to the development of the digital age。

Third，bet365 bonus bets annotation gradually becomes consensus。The current children’s bet365 bonus bets annotation shows three development characteristics。One，Development from manual annotation to computer automatic annotation。For example，2013，The children's multimodal spoken bet365 bonus bets constructed by Linyi University uses the multimodal annotation software ELAN for text transcription。Part 2，From pure language annotation to discourse annotation。Conversation Behavior、Verbal act、Paralanguage、Pragmatics、Language event、Emotional and other encodings appear in the bet365 bonus bets annotation specifications，This is a sign that bet365 bonus bets construction begins to pay attention to children’s discourse。Part 3，Annotation rules gradually form a consensus。Currently，The most widely used children's bet365 bonus bets specification and collection tool，is the CHILDES child language data exchange system built in 1984 by the International Children's Language Center at Carnegie Mellon University in the United States。This system also functions as bet365 bonus bets aggregation，In the World Preschool Children bet365 bonus bets，About 89% collected by CHILDES system；Most preschool children’s corpora also draw on the bet365 bonus bets annotation rules provided by CHILDES。Some children's bet365 bonus bets，Such as the spoken Chinese bet365 bonus bets of five to six-year-old preschool children in Singapore，Using "973 Contemporary Chinese Text bet365 bonus bets Word Segmentation、Part-of-speech tagging processing specifications”，And use it to annotate the Chinese language of Singaporean Chinese children。

　　Preschool children bet365 bonus betsConstruction content: “Three Consciousnesses”

bet365 bonus bets technology is the way to realize the construction of children's bet365 bonus bets，The content of the bet365 bonus bets reflects the ideas and concepts of construction。Inspect more than 300 official documents provided by the CHILDES platform，Refer to nearly a thousand literatures on children’s corpora，The development of preschool children’s bet365 bonus bets content in recent decades can be summarized as “three consciousnesses”。

Fusion consciousness。The awareness of integration in the construction of the bet365 bonus bets of world preschool children is mainly reflected in two aspects: First, the two major categories of "language structure" and "language function" are gradually integrating。Currently，In the World Preschool Children bet365 bonus bets，More than 230 people focus on language structure，About 66%，These corpora mainly focus on children’s speech、Vocabulary、Syntax、To build in five aspects including paralanguage (symbols) and literacy skills；More than 250 people focus on language functions，About 72% of the total，Construction content focuses on communicative intent、Language socialization、Discourse、Paralanguage (communication)、Communication strategies、Speech acts, etc.；Nearly 150 articles focus on both language structure and language function，Represents the construction direction that focuses on the integration of the two major categories of language structure and language function。

The second is the gradual integration of academic research and social application。Two major social fields of concern in the construction of the bet365 bonus bets of preschool children，is the research and development of children’s language intelligence technology and children’s language intervention treatment。Research and development of children’s language intelligence technology，Reflected in the one-way recognition of language and characters and the construction of "human-machine" two-way communication interaction，Reflected in the use of children’s language intelligence technology in the development of children’s language products，This is also the key to realizing the industrialization transformation of language in children’s bet365 bonus bets。Combining research on children’s language disorders with children’s language intervention treatment，Reflects the benevolent consciousness of bet365 bonus bets construction to provide language services for special children，This is why the construction of children's bet365 bonus bets can solve social language problems、Important areas for the benefit of society。

Multilingual awareness。According to incomplete statistics，About 50 languages ​​(including their regional variants and social variants) are included in the construction of the preschool children's bet365 bonus bets，The top 10 are English、Spanish、Chinese、French、Dutch、German、Japanese、Italian、Portuguese、Russian。Among them，The number of Chinese children's corpora accounts for about 9% of the total number of world constructions。In recent years，Presented in English、Spanish、Chinese、Mainly French，Language diversity pattern that quickly adds other languages ​​to the database。

The bet365 bonus bets of bilingual or multilingual preschool children is also constantly developing。There are currently more than 40 corpora of bilingual or multilingual preschool children，Covering about 30 languages ​​(including their regional and social varieties)，The top five languages ​​with the largest number of construction projects are English、Spanish、French、Chinese、Dutch。Should also see，Young children、Children in other languages、The issue of multilingual development of bilingual sign language children has become a hot topic in the 21st century，However, the current bet365 bonus bets construction still needs to pay more attention to such issues。The number of languages ​​included in the world’s preschool bet365 bonus bets is approximately 0% of human languages.7%，The number of languages ​​participating in the construction of the bet365 bonus bets of bilingual or multilingual preschool children in the world is about 0.4%，There is still a lot of room for development in the future。

Shared consciousness。Currently there are more than 160 children's corpora providing sharing services，About 46% of the total。The largest existing children’s bet365 bonus bets sharing platform is the CHILDES system，In the shareable children's bet365 bonus bets，More than 150 from CHILDES platform。From the perspective of historical development，The sharing rate of children’s bet365 bonus bets is on the rise。bet365 bonus bets of preschool children constructed in the 20th century，Providing shared services accounted for approximately 45% of the total construction during this period；21st century，The proportion of providing shared services increased to 54%。For example，Miyata bet365 bonus bets and others while providing bet365 bonus bets sharing services，Clearly stated that it will “protect the privacy of survey respondents”。On the basis of complying with basic ethical norms，The realization of bet365 bonus bets sharing complies with the development requirements of the era of resource co-construction and sharing。

Overall，Since the end of the 20th century，The construction of bet365 bonus bets of preschool children is booming。However, in the application of advanced technology、Academic Consciousness、Openness、Usage efficiency and other aspects still need to be improved。The construction of bet365 bonus bets for preschool children involves not only bet365 bonus bets linguistics、Children’s Linguistics、Children’s Studies、The development of computer science and other disciplines，It’s still about language education、Long-term undertakings such as cultural gene inheritance and global information equality，It is not enough to understand the construction of children's bet365 bonus bets only from the technical and content levels。Combined with today’s digital survival、The background of intelligent transformation，Need to explore the status of children’s bet365 bonus bets in the larger subject system and national strategy，In-depth study of ways to improve the level and reputation of Chinese children’s bet365 bonus bets construction，And consider issues such as equipping children with “intelligent playmates” and “intelligent teachers” in the future。
