Used Docker and Grobid 0.8.0, performing full text extraction from the following PDF:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10125888/pdf/10.1177_23328584231165919.pdf

XML fragment of the abstract and following text returned by Grobid below:

<abstract>
<div xmlns="http://www.tei-c.org/ns/1.0"><p>interpret algebraic expressions. This current study, therefore, tested the impacts of three educational technology interventions on algebraic understandin
g among students in Grade 7 across four conditions: (a) From Here to There (FH2T), (b) DragonBox 12+ (DragonBox), (c) Immediate Feedback, and (d) Active Control. The FH2T and DragonBox</p></div>
			</abstract>
		</profileDesc>
	</teiHeader>
	<text xml:lang="en">
		<body>
<div xmlns="http://www.tei-c.org/ns/1.0"><p>2 conditions represented use of game-based applications. Immediate Feedback entailed problem sets by using an online homework system, ASSISTments. For the
 purposes of this study, the Active Control condition mimicked traditional homework assignments while still using technology. Although this study independently investigated each of the three treatme
nt conditions to the Active Control condition, it was hypothesized that FH2T, an interactive game developed based on theories of perceptual learning and embodied cognition, might improve students' a
lgebraic understanding through aligning their attention to, actions on, and perception of algebraic notations with high-level mathematical concepts to a greater extent than would DragonBox or Immedi
ate Feedback.</p></div>

It appears that the abstract continues to be returned by Grobid as part of the body, but is not inside the abstract xml node as expected.

Hi @landryraccoon, thank you for reporting this issue and the related document.

Indeed, there are two problems here:

  • the whole the abstract is missing, instead, part of the first right column of the body is classified as abstract
  • the first page left column of the body is lost

It seems we can use it for training in the future
